DNA tests "inconclusive" in Bristol woman’s unsolved 1977 murder

Posted: June 29, 2013 at 1:47 pm

The long awaited DNA tests in the Shaun Ritterson case are finally in, and the results have shed little light on the 35-year-old murder mystery.

Unfortunately, due to the degradation of the evidence, the test results came back inconclusive, said Matt Weintraub, Bucks County's chief of prosecution. They couldn't implicate our suspect, or rule our suspect out.

Like all homicides, the 20-year-old Bristol woman's case will remain open, Weintraub said, but will no longer be an active investigation.

Personally, I'm disappointed, he said. But professionally I'm satisfied that we've done all that we can do to solve this case and bring some finality to it.

Ritterson was found dead on a Buckingham hillside in June 1977. She had been stabbed and disemboweled.

Numerous people were questioned, but an arrest was never made.

In 2011, the Bucks County District Attorney's Office granted reporters from Calkins MediaThe Courier Times and Intelligencer's parent company unprecedented access to the Ritterson files and evidence. A year of research and interviews led to the award-winning series The Girl on Church Hill, published in June 2012.

The reporters' work also spurred investigators to reopen the case. A task force of detectives and other law enforcement officials re-interviewed as many witnesses as they could find, and chased down leads provided by newspaper readers.

Police in both 1977 and 2012 showed interest in Ritterson's uncle, Harry Ritterson. Witnesses described his relationship with his niece as extremely close, and said they often socialized together at bars despite a 20-year age difference.

A reporter interviewed Harry Ritterson at his Easton home last year. He said he knew he'd been blamed for his niece's murder and wanted to clear his name. Ritterson told the reporter that he wanted to speak with investigators and offered to take a DNA test. He then cut off all contact with the reporter.

Watson: ‘DNA was my only gold rush’

Posted: at 1:47 pm

STORY HIGHLIGHTS

Cold Spring Harbor, New York (CNN) -- At 85, James Watson still plays tennis every week. His hips and knees haven't given out yet, he says, and he likes grass courts.

"I try and play people who can hit the ball hard," he said Tuesday at Cold Spring Harbor Laboratory, a Long Island, New York, research institution he directed for 25 years.

Watson has always gone up against tough competition, especially in science. Most famously, in 1953, he and Francis Crick figured out that DNA, the molecule of life, has a double helix structure, beating their rival Linus Pauling to the answer.

Solving the DNA structure set the stage for the foundation of much of modern biology, as scientists use insights about DNA to develop disease treatments, trace the inheritance of physical traits and explore how conditions can be passed down from generation to generation.

Having shared the Nobel Prize for the discovery with Crick and Maurice Wilkins in 1962, who are now both deceased, Watson is aware that he perhaps has no competitor in the title of most famous living scientist.

"That's really saying, there's not been another DNA," he said, clad in khaki Bermuda shorts, beige socks and brown loafers. "All you can say is that you were very lucky. You were born at the right time and your parents gave you books when you were young."

DNA Found Outside Genes Plays Largely Unknown, Potentially Vital Roles

Posted: at 3:46 pm

UCSF Study Identifies Thousands of Previously Unknown RNA Molecules

Newswise A new UC San Francisco study highlights the potential importance of the vast majority of human DNA that lies outside of genes within the cell.

The researchers found that about 85 percent of these stretches of DNA make RNA, a molecule that increasingly is being found to play important roles within cells. They also determined that this RNA-making DNA is more likely than other non-gene DNA regions to be associated with inherited disease risks.

The study, published in the free online journal PLOS Genetics on June 20, 2013, is one of the most extensive examinations of the human genome ever undertaken to see which stretches of DNA outside of genes make RNA and which do not.

The researchers senior author and RNA expert Michael McManus, PhD, UCSF associate professor of microbiology and immunology and a member of the UCSF Diabetes Center, graduate student Ian Vaughn, and postdoctoral fellow Matthew Hangauer, PhD identified thousands of previously unknown, unique RNA sequences.

Now that we realize that all these RNA molecules exist and have identified them, the struggle is to understand which are going to have a function that is important, McManus said. It may take decades to determine this.

The RNA most familiar from textbooks is the messenger RNA that is transcribed from DNA in genes and that encodes the amino acid building blocks of proteins. The transcription of messenger RNA from DNA is a key step in protein production. The rest of the DNA on the cells chromosomes was once thought not to be transcribed into RNA, and was referred to as junk DNA.

Today, scientists estimate that only 1.5 percent of the genome consists of genes, McManus said. But over the last two decades other kinds of RNA have been identified that are transcribed from DNA outside of gene regions. Some of these RNA molecules play important biological roles, but scientists debate whether few or most of these RNA molecules are likely to be biologically significant.

Among the RNA transcribed by the DNA outside of genes, the UCSF researchers identified thousands of previously unknown RNA sequences of a type called lincRNA. So far, only a handful of lincRNA molecules are known to play significant roles in human biology, McManus said.

Previous research has shown that lincRNAs can have diverse functions. Some control the activity of genes that encode proteins. Others guide protein production in alternative ways.
