In Brief Scientists are now able to retrieve and analyze the DNA of ancient human ancestors from sediment, opening up a world of possibility for exploring early human evolution in the absence of fossils and bones. The Dirt on DNA

German scientists just made a major breakthrough in sequencing the DNA of our ancient ancestors. While researchers have long relied on painstaking work and pure good luck to uncover the fossilized remains of our predecessors, a new technique has allowed scientists to pull DNA from something far more abundant: dirt.

Scientists have understood for years that genetic material from a decomposing entity whether animal, plant, or human is released into the surrounding sediment and can remain there for a long time. The problem is theres a lot of it and its all mixed up. Parsing out only human DNA deposits from even a tablespoon of dirt has traditionally been very difficult to do.

Led by Viviane Slon, scientists at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have developed a process for retrieving and sequencing those DNA deposits, and they are now the first researchers to recover ancient human DNA directly from sediment. To do so, they created molecules that would target and extract DNA from mammals, specifically mitochondrial DNA, which is more abundant.The team presented its findings in the journal Science last week.

Slons team shines a new light onthe Denisovans,a cousin to our Neanderthal ancestors that we know very little about. So far, scientists have only recovered a fossilized finger bone and a couple of teeth, both of which came from a single cave in Siberia. If the technique for analyzing DNA from dirt becomes a regular part of field work, theres the potential for discovering more evidence of this ancient ancestor in places without fossils. It will teach us more about what early humans were doing outside of the cavesin which they lived (and apparently died), including migratory information.

For paleontologists and archeologists, the prospect of no longer having to rely quite so heavily on the exciting but relatively rare discovery of fossils will likely come as a relief. Even when they are able to find a fossil, putting it through the paces for sequencing can compromise its integrity as a specimen, making researchers no friend to museum curators or civilizations looking to preserve the remains of their ancient ancestors.

Perhaps most exciting of all, though, is the fact that being able to retrieve DNA in the absence of bones could add new branches to humanitys family tree, giving researchers insight into early humans that we have yet to find skeletal evidence of.

DNA sketch of Angie Dodge's killer (Photo: Idaho Falls Police)

IDAHO FALLS -- Two decades after 18-year-old Angie Dodge was raped and stabbed to death in her Idaho Falls apartment, police are leveraging DNA technology to get their first tentative look at the killer's face.

The DNA profile sketch, released Wednesday, was made possible by Parabon Nanolabs, a Virginiabased DNA technology company. Although no match has been found for the DNA on Dodge's body after the 1996 slaying, the company was able to use the killer's genetic material to determine his likely hair, eye and skin color.

One of the profiles shows the suspect at about age 25, while the other shows how he would look age-progressed to his forties - believed to be the killer's current age.

According to the sketch, the man who killed Dodge has brown eyes, brown or blond hair, and a normal body mass index.The suspect is white with skin that is fair or very fair, and of northern European ancestry, the profile suggests.

MORE: Tapp released from prison after 20 years

The information released in the DNA snapshot may not be 100 percent accurate, Parabon Nanolabs says. But the Idaho Falls Police Departmetnt believes it may get detectives a step closer to finding the killer who has eluded justice in Dodge's death.

In a statement, Idaho Falls Police Chief Mark McBride said detectives are committed to getting an answer, no matter how long it takes.

The Idaho Falls Police Department has spent more time and money investigating this crime than any other crime in the history of this department, he said. But the resources directed to this case are quintessential to solving it, and we are determined to bring a resolution to this heinous crime. We owe it to the Dodge family and our citizens and therefore, this case will remain as high of a priority as it has been since 1996.

Police say two DNA profiles were collected at the crime scene, indicating that more than one person was involved in the attack. Under current technology, only one of the two samples was viable to be tested.

That testing was integral in getting former Idaho Falls resident Chris Tapp released from prison after 20 years behind bars. Tapp, who prosecutors had said held Dodge down while another man sexually assaulted and killed her, has long maintained he was coerced into signing a false confession.

Tapp's convictions were not overturned, but a judge resentenced him to time served and ordered him released from prison in March amid doubts about whether he was connected to the crime. Even the murdered teen's mother, Carol Dodge, had joined activists and the Idaho Innocence Project in calling for Tapp's release.

In an interview with KTVB after his release last month, Tapp said he still did not want anyone to forget about the cold case.

Everybody is excited and happy that I'm released and free, but also on the other side of the coin theyre forgetting the most important thing: There's still an unsolved murder," he said.

Idaho Falls Police and Channel Blend of Idaho Falls have set up a 24-hour tipline for anyone who recognizes the man in the DNA profile sketch or knows anything about the murder.

The tipline number is 18009271239. Callers can leave tips anonymously, or an provide a name and contact information for a callback from detectives. Every tip will be followed up on by detectives, police say.

Police say the department has already spent more than $43,000 in evidence extraction, analysis, DNA profiling, and travel to follow up on leads over the past four years, as well as staffing and overtime assigned to the case.

"This is a testament of our commitment and desire to utilize available and cuttingedge technologies to finding our killer," McBride said. "We are hopeful and excited this new phenotype sketch will help us garner new leads into the Dodge homicide."

Some Mothers Boy, killed in a train accident nearly a century ago and buried as an unknown in a Georgetown cemetery, is finally coming home to rest beside his mother and father.

Results of DNA tests are about a month away, but the Haynes family in Pulaski County seems assured Frank A. Haynes, interred for 96 years, is one of them. They are planning to bring his scant remains, exhumed in March, back home to be buried beside his parents in the Newell cemetery at Bronston.

Haynes, 19, was killed in a train accident in Georgetown April 1, 1921. His head apparently was mutilated by wheels on the train as he and a companion attempted to switch directions by jumping from one train to another.

Some newspapers in the area identified Haynes a short time after his death, but no official identification was made and he was buried as an unknown. Communication during the early 20th century was mainly word of mouth and distance between the accident site in Georgetown and his family in Bronston was light years apart.

Someone, somebody, put up a tombstone inscribed: Some Mothers Boy/Killed/April 1, 1921/Interred/April 14, 1921/Contributed by Friends.

Haynes death was legend among members of the Haynes family during the past century. His many relatives in Bronston, Burnside and Somerset knew he was killed by a train; the story was told time and time again. However, they didnt know his burial place until recent publicity surrounding an investigation by J. Todd Matthews, director, Case Management and Communications, National Missing and Unidentified Persons System (NamUs).

Efforts by Matthews and NamUs generated publicity that informed relatives in this area where the body was buried. Initially, as recent stories surfaced, Haynes age was given as 17. However, Frank M. Haynes, a nephew who lives at 51 Muncey Lane, Somerset, said family Bible records list the dead mans birthdate as March 2, 1902, making him 19 when he was killed.

My father, Fred, told me the story many times, said Frank M. Haynes. He (Frank A. Haynes) and another boy jumped a train in Burnside. For some reason, at Georgetown, they decided to switch directions.

Both boys jumped from the northbound train to a southbound train (Royal Palm). The other boy made the jump. Frank didnt. The train ran over his head, probably leaving him unidentifiable, said Frank M. Haynes.

The dead boys companion reportedly was detained in Somerset for questioning. However, his name was not recorded and nobody knows who he was or where he went.

Matthews was in Somerset Tuesday to collect female DNA samples from Mamie Hahn, a niece who lives in Twin Lakes subdivision at Bronston. Originally, plans were to take a DNA sample from Margaret Haynes Bell, another niece from Burnside. However, Matthews explained it was necessary to get the sample from Hahn on the dead boys maternal side. Members of the family gathered Tuesday in the Wal-Mart parking lot where DNA and FRS (Family Reference Samples) were taken.

A family spokesperson said Richard New, manager of Southern Oaks Funeral Home, will provide an appropriate container in which to bury the few bones and teeth that remain in the grave after 96 years.

Frank A. Haynes was one of 12 children of Frank Haynes Jr. and Mignona Haynes of Bronston.

DNA is helping solve 96-year-old mystery - Commonwealth Journal's History

May 4, 2017 by Matt Williams, Universe Today An interdisciplinary team from MIT (with support from NASA) is seeking to create an instrument that can performing in-situ test for life. Credit: setg.mit.edu

In 2015, then-NASA Chief Scientist Ellen Stofan stated that, "I believe we are going to have strong indications of life beyond Earth in the next decade and definite evidence in the next 10 to 20 years." With multiple missions scheduled to search foe evidence of life (past and present) on Mars and in the outer solar system, this hardly seems like an unrealistic appraisal.

But of course, finding evidence of life is no easy task. In addition to concerns over contamination, there is also the and the hazards the comes with operating in extreme environments which looking for life in the solar system will certainly involve. All of these concerns were raised at a new FISO conference titled "Towards In-Situ Sequencing for Life Detection", hosted by Christopher Carr of MIT.

Carr is a research scientist with MIT's Department of Earth, Atmospheric and Planetary Sciences (EAPS) and a Research Fellow with the Department of Molecular Biology at Massachusetts General Hospital. For almost 20 years, he has dedicated himself to the study of life and the search for it on other planets. Hence why he is also the science principal investigator (PI) of the Search for Extra-Terrestrial Genomes (SETG) instrument.

Led by Dr. Maria T. Zuber the E. A. Griswold Professor of Geophysics at MIT and the head of EAPS the inter-disciplinary group behind SETG includes researchers and scientists from MIT, Caltech, Brown University, arvard, and Claremont Biosolutions. With support from NASA, the SETG team has been working towards the development of a system that can test for life in-situ.

Introducing the search for extra-terrestrial life, Carr described the basic approach as follows:

"We could look for life as we don't know it. But I think it's important to start from life as we know it to extract both properties of life and features of life, and consider whether we should be looking for life as we know it as well, in the context of searching for life beyond Earth."

Towards this end, the SETG team seeks to leverage recent developments in in-situ biological testing to create an instrument that can be used by robotic missions. These developments include the creation of portable DNA/RNA testing devices like the MinION, as well as the Biomolecule Sequencer investigation. Performed by astronaut Kate Rubin in 2016, this was first-ever DNA sequencing to take place aboard the International Space Station.

Building on these, and the upcoming Genes in Space program which will allow ISS crews to sequence and research DNA samples on site the SETG team is looking to create an instrument that can isolate, detect, and classify any DNA or RNA-based organisms in extra-terrestrial environments. In the process, it will allow scientists to test the hypothesis that life on Mars and other locations in the solar system (if it exists) is related to life on Earth.

To break this hypothesis down, it is a widely accepted theory that the synthesis of complex organics which includes nucleobases and ribose precursors occurred early in the history of the solar system and took place within the Solar nebula from which the planets all formed. These organics may have then been delivered by comets and meteorites to multiple potentially-habitable zones during the Late Heavy Bombardment period.

Known as lithopansermia, this theory is a slight twist on the idea that life is distributed throughout the cosmos by comets, asteroids and planetoids (aka. panspermia). In the case of Earth and Mars, evidence that life might be related is based in part on meteorite samples that are known to have come to Earth from the Red Planet. These were themselves the product of asteroids striking Mars and kicking up ejecta that was eventually captured by Earth.

By investigating locations like Mars, Europa and Enceladus, scientists will also be able to engage in a more direct approach when it comes to searching for life. As Carr explained:

"There's a couple main approaches. We can take an indirect approach, looking at some of the recently identified exoplanets. And the hope is that with the James Webb Space Telescope and other ground-based telescopes and space-based telescopes, that we will be in a position to begin imaging the atmospheres of exoplanets in much greater detail than characterization of those exoplanets has [allowed for] to date. And that will give us high-end, it will give the ability to look at many different potential worlds. But it's not going to allow us to go there. And we will only have indirect evidence through, for example, atmospheric spectra."

Mars, Europa and Enceladus present a direct opportunity to find life since all have demonstrated conditions that are (or were) conducive to life. Whereas there is ample evidence that Mars once had liquid water on its surface, Europa and Enceladus both have subsurface oceans and have shown evidence of being geologically active. Hence, any mission to these worlds would be tasked with looking in the right locations to spot evidence of life.

On Mars, Carr notes, this will come down to looking in places there there is a water-cycle, and will likely involve some a little spelunking:

"I think our best bet is to access the subsurface. And this is very hard. We need to drill, or otherwise access regions below the reach of space radiation which could destroy organic materiel. And one possibility is to go to fresh impact craters. These impact craters could expose material that wasn't radiation-processed. And maybe a region where we might want to go would be somewhere where a fresh impact crater could connect to a deeper subsurface network where we could get access to material perhaps coming out of the subsurface. I think that is probably our best bet for finding life on Mars today at the moment. And one place we could look would be within caves; for example, a lava tube or some other kind of cave system that could offer UV-radiation shielding and maybe also provide some access to deeper regions within the Martian surface."

As for "ocean worlds" like Enceladus, looking for signs of life would likely involve exploring around its southern polar region where tall plumes of water have been observed and studied in the past. On Europa, it would likely involve seeking out "chaos regions", the spots where there may be interactions between the surface ice and the interior ocean.

Exploring these environments naturally presents some serious engineering challenges. For starters, it would require the extensive planetary protections to ensure that contamination was prevented. These protections would also be necessary to ensure that false positives were avoided. Nothing worse than discovering a strain of DNA on another astronomical body, only to realize that it was actually a skin flake that fell into the scanner before launch!

And then there are the difficulties posed by operating a robotic mission in an extreme environment. On Mars, there is always the issue of solar radiation and dust storms. But on Europa, there is the added danger posed by Jupiter's intense magnetic environment. Exploring water plumes coming from Enceladus is also very challenging for an orbiter that would most likely be speeding past the planet at the time.

But given the potential for scientific breakthroughs, such a mission it is well worth the aches and pains. Not only would it allow astronomers to test theories about the evolution and distribution of life in our solar system, it could also facilitate the development of crucial space exploration technologies, and result in some serious commercial applications.

Looking to the future, advances in synthetic biology are expected to lead to new treatments for diseases and the ability to 3-D print biological tissues (aka. "bioprinting"). It will also help ensure human health in space by addressing bone density loss, muscle atrophy, and diminished organ and immune-function. And then there's the ability to grow organisms specially-designed for life on other planets (can you say terraforming?)

On top of all that, the ability to conduct in-situ searches for life on other Solar planets also presents scientists with the opportunity to answer a burning question, one which they've struggled with for decades. In short, is carbon-based life universal? So far, any and all attempts to answer this question have been largely theoretical and have involved the "low hanging fruit variety" where we have looked for signs of life as we know it, using mainly indirect methods.

By finding examples that come from environments other than Earth, we would be taking some crucial steps towards preparing ourselves for the kinds of "close encounters" that could be happening down the road.

Western spotted skunks striped skunks' smaller cousins that stand on their "hands" to blast their smelly defensive spray are helping scientists piece together a picture of how ancient climate change shaped animal populations millions of years ago, and could provide clues for how present climate change may affect animals alive today.

These endearing and widely distributed skunks have been around for about 1 million years and live in a range of habitats across western North America. But even though the skunks all belong to one species,Spilogale gracilis, genetic differences divide them into three distinct groups that are known as clades, and scientists have puzzled over what might have driven these changes in the skunks' DNA. [The 12 Weirdest Animal Discoveries]

Researchers investigating these adorable little stinkers recently discovered the likely scenario that led to these genetic divisions ancient climate change during the Pleistocene ice age, as glaciers divided skunk populations into habitats isolated from each other.

Unlike the bold bandsof white furlining the black backs of striped skunks, western spotted skunks' markings curve and twine like the walls of a maze, with a single large spot marking the center of their heads. They are the smallest of the North American skunks, with males measuring about 16 inches (41 centimeters) in length and weighing about 22 ounces (630 grams), according toa species descriptionby the Montana Natural Heritage Program and Montana Fish, Wildlife and Parks.

Western spotted skunks perform "handstands" just before they spray.

Because their distribution is so broad from British Columbia to northern Mexico, and from California to the central Great Plains groups of skunks could potentially be separated from each other by manynatural geographical barriers, such are rivers and mountain ranges. Scientists wanted to know whether geography could explain how skunk populations separated from each other and evolved unique genetic signatures, or if other land-shaping factors might have played a part, study lead author Adam Ferguson, collection manager of mammals at the Field Museum of Natural History, told Live Science.

"We were interested in whether we would see if genetic breaks are associated with older events major biogeographic events, like the Sierra, the Rockies, the Rio Grande or with climate change," Ferguson explained.

In general, skunks aren't well-studied, probably because working with them comes with an odious olfactory price "even their tissues stink," Ferguson said. In fact, during each season of fieldwork, he puts aside what will be "the skunk clothes," an outfit that sometimes must be permanently retired when the season ends, he said.

Study lead author Adam Fergusun wearing impromptu Kleenex nose plugs not to block the smell of his study subject, but because he had a cold.

For the study, the scientists sampled genetic data from 97 skunks representing a range of habitats and climates in thesouthwestern U.S.But the genetic differences that separated them didn't map to geographic features. For example, two skunk populations divided by mountains were mostly identical on a genetic level, the study authors found.

By modeling climate conditions during theice ageglacial maximum the period when ice covered the most land mass the researchers discovered that advancing glaciers could have effectively isolated habitat "refuges" from each other, allowing genetic differences to evolve in separated animal groups.

Their findings help to fill in the picture of how ancient climate change affected not only the western spotted skunks, but possibly other animals as well large and small that shared the skunks' habitats across the southwestern U.S. And this could help scientists predict how ecosystems and their inhabitants might be affected by present-day climate change, Ferguson said.

"If we have data from rodents, bats, small carnivores, large carnivores, reptiles, birds, we can say, 'How as a whole would theSonoran Desert communityrespond potentially to climate change across the board?' You can make these general predictions of how climate change might affect an entire community not just a single species," he told Live Science.

The findings were published online today (May 3) in the journalEcology and Evolution.

SANTA ANA A carjacker from Orange has been sentenced to three years in prison after authorities identified him through DNA he left on a cigarette in the recovered car.

Gary Munoz, 30, was arrested, charged and convicted in less than two months, thanks to the countys RAPID DNA program, the Orange County District Attorneys Office said in a Tuesday statement.

On March 9 at about 3:30 p.m., Munoz approached an idling car in a parking lot off of Imperial Highway in Brea, prosecutors said. Awoman was in the passenger seat while the driver was out looking for an ATM machine.

Munoz forced the woman out and then fled.

Brea police found the car parked less than two miles away on Jasmine Drive. Among the evidence, officers collected a used cigarette in the cup holder and submitted it for forensic analysis.

On March 15, investigators got a match to Munozs DNA profile in the local database; his DNA was in the system because of a prior conviction. He was arrested on March 22 and pleaded guilty on April 27, accepting the courts offer of three years, to one felony count of carjacking.

The countys RAPID DNA program, which launched in 2015, uses aninstrument that can generate a DNA profile from evidence collected at a crime scene in less than two hours, prosecutors said.

The Edneyville crime lab adjacent to the Henderson County Justice Center is slated to open in June. That facility will begin doing DNA testing starting in September, which should help improve the turnaround time for test results. (Photo credit: WLOS staff)

Dominique Harris, who is in jail on $190,000 bond, is charged with second-degree rape and kidnapping. The alleged crime took place in West Asheville last May. But it took months for results of a rape kit to come back, allowing Asheville police to arrest Harris.

Attorney General Josh Stein said he was familiar with the case.

I think it took about eight months for the lab to turn around the results in this test, Stein said. And, in my view, eight months is too long.

Every day that goes by that those kits aren't back and we don't have the answers, nothing with the justice system can begin, and it builds on that anxiety, said Andi Craven, program director for Henderson Countys Justice Center.

Craven is not familiar with Harris case, but she is well aware of long-reported backlog problems with DNA testing for rape kits.

Stein said salaries for forensic scientists have been raised to $50,000-$65,000. He said that has helped with retention of important staff.

The Edneyville crime lab adjacent to the Henderson County Justice Center is slated to open in June. That facility will begin doing DNA testing starting in September. The goal, Stein said, is to reduce turnaround times to less than eight months, which he said is the average time for evidence analysis. Scientists now training in Raleigh will begin working on DNA testing as soon as their training is complete. Lab techs, Stein said, have also been hired to free up scientists to do testing.

Crime lab backlog leads to 8-month delay on rape kit DNA analysis - WLOS

Nebraska Gov. Pete Ricketts said the state will take swift action to obtain inmates DNA samples in light of a World-Herald report Sunday that revealed that 73 inmates have refused to comply with state law requiring convicted felons to submit a DNA sample.

I agree public safety is at risk if these DNA samples are not collected, Ricketts said in a statement. I understand our options to obtain these samples and will take swift action.

He didnt clarify what that action might be.

Nebraska Attorney General Doug Peterson said Tuesday that he wants to stick with the Corrections Departments current methodical plan for progressive discipline misconduct reports, loss of privileges and the possible loss of good-behavior credit.

Some law enforcement officials, including Douglas County Attorney Don Kleine and Omaha Police Chief Todd Schmaderer, have called on Corrections to immediately use force to obtain a refusing prisoners DNA sample.

I believe, ultimately, we can, Peterson said.

Peterson said, however, that he wants to be diligent about allowing the progressive discipline process to work because that will give us a much better idea of where we stand with the inmates who are refusing. But I cant estimate how quickly Corrections will be able to do that. They know its a priority for us.

Members of the Nebraska Legislature, meanwhile, were exploring possible actions to investigate the states embattled prison system burdened by overcrowding, understaffing, uprisings and inmates deaths.

State senators expressed dismay over the April 15 death of inmate Terry Berry. Berry, a 22-year-old check forger who had minimal time left in prison was placed in the same cell with Patrick Schroeder, a convicted killer serving a life sentence. Schroeder now stands charged with first-degree murder after authorities allege he strangled Berry with a towel.

Prison officials also placed inmate Christine Bordeaux in the same cell as Erica Jenkins the cousin she testified against and helped convict of murder. Authorities allege Jenkins beat Bordeaux to a pulp at the York womens prison. Bordeaux survived with serious injuries.

Sen. Bob Krist of Omaha, a member of the Judiciary Committee, said state officials have been trying to address larger issues of overcrowding and understaffing in Nebraskas prisons.

But just as were paying attention to the big things, Krist said, it seems that Rome is burning right under our nose operationally.

Krist said he soon will propose a legislative resolution calling on his colleagues to convene another special committee this summer to investigate the management problems that have, among other things, led to five deaths in Nebraskas prisons in the past two years. The committee would be modeled after a prison investigative committee that held hearings and dominated headlines in 2014.

Sen. Ernie Chambers of Omaha said he supports the rejuvenation of the committee, in part to probe the five recent deaths and the placement of Bordeaux with the woman she testified against.

People are being killed, theyre being assaulted, both inmates and employees, there have been riots, great destruction of property, inmates endangered when fires took place, and theyve been kept in their cells with all the smoke, Chambers said. Its just more than ought to be tolerated.

Other senators werent so sure a separate committee is needed.

Sen. Laura Ebke of Crete, chairwoman of the Judiciary Committee, said this week she does not favor relaunching the prison investigative committee.

She said she thinks most of the eight members of the Judiciary Committee may opt instead to bring Scott Frakes, director of the Department of Correctional Services, before them to answer questions on prison issues.

Ebke expressed concerns about the DNA testing issue, but said shes inclined to believe the Legislature can get answers without going to the lengths taken in 2014.

I feel pretty strongly about this. I dont want to overburden Corrections staff or micromanage too much, she said. I dont want to go on a broad, sweeping investigation and take up more of their time at a time theyre trying to deal with multiple issues.

State Sen. Paul Schumacher of Columbus said he also thinks the Judiciary Committee can tackle the matter. However, Schumacher said, many of these issues wont be resolved without biting the bullet and addressing Nebraskas overcrowded prisons.

Investigating something that you already know the answer to isnt terribly fruitful, Schumacher said. I dont think its a new phenomenon in our prisons; its just a continuation of the same old stuff. It appears to me these most recent things should have been caught by common sense.

Krist said the DNA issue smacks of the problems that caused state senators to commission the 2014 investigative committee. That investigation, initiated to look into spree killer Nikko Jenkins release, was expanded after The World-Herald revealed that prison officials had illegally set early release dates for 750 prisoners.

Senators noted similarities between the DNA refusals and the 2014 problems: violent offenders benefiting from prisons inaction; issues of where inmates are placed; and prison officials not acting decisively after a Nebraska Supreme Court ruling.

Ricketts said he has spoken with Frakes, Peterson and Kleine about the DNA collection issue.

The issue dates to 1997, when the Nebraska Legislature first required convicted sex offenders to submit a DNA sample. Then-Nebraska Attorney General Don Stenberg issued an opinion advising Corrections that, based on state senators comments, they could not use force to obtain an inmates DNA. However, two months later the Nebraska Supreme Court upheld Omaha polices use of force to extract blood from a serial rapist.

Eventually, Peterson said, the state may need to go to the courts to get an order to allow the use of force to obtain a refusing prisoners DNA.

Chambers said he is against forced DNA collection from convicted felons a process that is allowed in several states. He called it the crowning crime against humanity.

The real crime, Kleine said, is a victim not knowing the identity of his or her attacker because Corrections has failed to collect an inmates DNA.

In their phone conversation, Kleine said, Ricketts indicated he had been unaware of the DNA refusals.

The governor was very adamant that he wanted something to happen, Kleine said. So that was encouraging.
