STONY BROOK, N.Y.--(BUSINESS WIRE)--Applied DNA Sciences, Inc. (NASDAQ: APDN) (the Company), a leader in cell-free, enzymatic DNA production, has been increasing its engagement with all stakeholders in anticipation of the June 21, 2022, effective date of the rebuttable presumption standard under the Uyghur Forced Labor Prevention Act (UFLPA) signed into law on December 23, 2021. Under the UFLPA, all imports that originate from China's Xinjiang Uyghur Autonomous Region (XUAR) or otherwise use Uyghur or other minorities for forced labor in China, are excluded from entry into the U.S. by the Customs and Border Protection agency (CBP) of the Department of Homeland Security (DHS).

On June 17, DHS issued its much-anticipated Implementation Strategy (the Strategy) for the rebuttable presumption standard under the UFLPA. In this new report, DHS has, for the first time, identified DNA traceability and isotopic testing - both central components of Applied DNAs CertainT authenticity platform - as evidence that importers may present to potentially prove that items do not originate in XUAR or may have benefitted from forced labor.

The UFLPA seeks to insulate U.S. companies and consumers from complicity in forced labor practices in XUAR, which produces nearly 20% of global cotton1. Commercially available for almost a decade, Applied DNAs CertainT platform is a multi-layered textile traceability solution that offers proof of product origin, authenticity, and sustainability.

Catalyzed by the imminent implementation of the UFLPA, Applied DNA is acquiring DNA traceability and isotopic testing clients intent on establishing proof of origin to comply with the UFLPA in the near-term with the long-term objective of securing their global supply chains using CertainT. Louis Dreyfus Company B.V., the Companys cotton merchant partner, recently received a request to ship the first quantities of traceable tagged cotton that is directly attributable to the UFLPA.

In GFY21, CPB used its forced labor authority to detain almost 1,500 shipments with a value of almost $500 million. The Biden Administrations budget request for GFY23, which begins on October 1, 2022, calls for $70 million to implement the UFLPA, to hire 300 additional CBP inspectors, and screen 11.5 times as many shipments for forced labor violations as is being undertaken currently.

CertainT is a 100% American solution that is unique in its ability to offer multiple traceability solutions, including DNA traceability and isotopic testing that are both cited (see page 49 in the link) in the Strategy. We believe that the high bar established by the UFLPA with its documentary and supply chain management requirements place a burden on importers that cannot be adequately met by fungible reporting frameworks, such as conventional paper- or electronic systems, stated Dr. James A. Hayward, president, and CEO, Applied DNA.

Coming on the heels of Customs and Border Protections budget request to fully implement the Strategy, we are pleased to see agreement at the regulatory level as a precursor to potentially broader industry adoption, continued Dr. Hayward. As a U.S.-based company, we applaud the imperative with which the Strategy is moving federal law towards action and, not only for its potential to be transformative to our supply chain security business, but also to deliver clear societal and ethical benefits to the American consumer. With the 2022 cotton ginning season soon upon us, we stand ready to deliver DNA-tagged American cotton to meet brand demand driven by the UFLPA.

Andrew Samet, principal at trade consulting firm Sorini, Samet & Associates and textile lobbyist for Applied DNA, said, It is clear from the new strategy document that Homeland Security officials and others in the U.S. government recognize that documentary traceability is insufficient. Technology solutions proving origin, such as DNA tagging and isotopic analysis, are for the first time being referenced and are the emerging framework both for authentication and enforcement forced labor is a key driver for this secular change now officially underway.

Sophia Majeed, principal clinical scientist and project team lead in the 23andMe Therapeutics group, knows how volatile and potentially controversial the biotechnology field is. The company, which has 579 employees, has been through a couple of contentious rounds with the FDA over whether its products are safe medical devices. Theres also the ethical question of what 23andMe does with the data its collected from people after theyve received their DNA results.

For Majeed, the workplace has to be a safe and secure environment. 23andMe workplace culture encourages people to speak out and be their authentic selves, Majeed said. Our CEO, Anne Wojcicki, sets the tone by encouraging people to have difficult conversations, and she doesnt shy away from responding to tough questions.

The San Francisco Chronicles Top Workplaces in the Bay Area competition honors the best workplaces in the Bay Area, as recognized by their employees. This is the 13th year Energage has surveyed Bay Area employees and its first year working with The San Francisco Chronicle.

Wojcicki founded the Sunnyvale-based 23andMe in 2006 with Linda Avey and Paul Cusenza. Avey and Cusenza are no longer with the company. The direct-to-consumer DNA testing company enables consumers to test for ancestry and health risks through genetic information obtained from saliva samples. It ranked second among large companies in the 2022 Bay Area Top Workplaces survey.

The 23andMe lab analyzes the genetic information in the saliva and digitally returns the results to the buyer. There are three levels of testing kits (Ancestry and Traits, Health and Traits, and 23andMe+ Membership), and the process could eventually unlock genetic information that will predict certain illnesses or help generate therapies and cures. The company is named for the 23 pairs of chromosomes in a normal human cell.

I appreciate working here, not because there arent things that can be improved, but because we value each others humanity, and we acknowledge that we must continue to work to be the best versions of ourselves, Majeed said.

That sentiment is echoed by employees in the survey:

I feel that I am challenged to grow and do my best work while working on interesting projects that positively impact our customers lives. I am fully utilized doing work that is meaningful to myself and others.

I trust Anne, the CEO, to lead by example. I care deeply about my colleagues and enjoy working with them. I feel valued and included. My manager is supportive and helpful. When I disagree with a direction, I feel encouraged to speak up and heard if I do. Im excited about the future. Most importantly, I believe in the work were doing and value how impactful and important it is.

My manager provides feedback and support as problems arise, identifies opportunities for me to grow, and has given me responsibilities that have encouraged skill building. Most importantly, my manager has built a strong and trusting relationship with me, which helps me feel like I can try new things and fail without danger of retaliation.

To me, workplace culture determines social norms and defines acceptable behaviors at work. It reflects the core values of the company and senior leadership.

Majeed has seen the company grow not just in size but in understanding how to grow in a way that supports its employees as well.

I am surprised most by the cultural evolution at 23andMe in the last few years, Majeed said. I have seen our commitment to authenticity manifest in a more self-aware and compassionate culture; one that values feedback, self-improvement and honesty.

TikTok couple Carley and Mercedes have revealed theyre doing a DNA test after finding out that they may be related to each other.

When looking for a relationship, nearly everyones worst nightmare is accidentally falling in love with a long-lost family member.

But, what if you fall in love with someone and dont find out that you may be related until months down the line?

TikTok creators Carley and Mercedes are going through just that, revealing that theyre doing a DNA test after finding out they may be half-sisters.

In early June 2022, Carley and Mercedes posted a video to their joint TikTok page that after two years of dating each other they learned their moms both slept with the same guy.

Due to that, they realized that they might be half-sisters.Their story quickly went viral, leading to millions of views.

While Carley and Mercedes havent explicitly said how they feel about possibly being sisters, viewers have been quick to share their thoughts.

Many users explained that they do look like siblings, and could even be twins, while others have mentioned theyre not even sure how theyd react to the situation.

Another hot topic in the comments is whether or not the two should stay together if they do find out theyre related. Viewers are split between what theyd do in Carley and Mercedes shoes with many explaining that theyd stay together.

Either way, its going to be a few more weeks until they find out the results and well be sure to update you when that time comes. In the meantime, head over to our TikTok hub to check out more viral trends and other news.

METAIRIE, La. -- Dennis Allen's transition to the New Orleans Saints' head coaching job has been a smooth one by all accounts.

Well, mostly.

Were such creatures of habit, said the Saints former defensive coordinator, who confessed to one particular misstep from a few weeks ago. I left the locker room and went up to my office, and I just walked up the back way and down the hall and walked into what is now [co-defensive coordinator] Ryan Nielsens office. And I was like, Oh damn, I just walked into the wrong office.

He was in there, and I started up some sort of conversation and acted like I needed to talk to him. And then at the end, I was like, I gotta admit something: I really just came to the wrong office.'"

To be fair, though, Allen has made a point of trying to keep things as normal as possible so far this offseason.

The vibe has been much different than it was when Allens mentor, Sean Payton, first arrived in New Orleans 16 years ago and did all he could to change the culture. Payton made tweaks to just about everything, down to signs hanging in the locker room and jersey colors at home games.

Allen, on the other hand, is proud of the culture he helped Payton and much of this current Saints coaching staff and roster build over the course of five straight winning seasons from 2017 to 2021 before Payton decided to step away from the job in January.

Why would I change things just to change them? Allen said. Weve done a lot of good stuff around here. So youre gonna see a lot of the same stuff.

Now, the way I present the message may be just a little bit different than the way Sean presented it ... kind of putting my own flair on it.

Players and coaches seem to widely appreciate that approach from the 49-year-old Allen, who is trying to find the success in his second head coaching stint that eluded him when he struggled to an 8-28 record with a much less established Oakland Raiders from 2012 to 2014.

Thats huge, just keeping the DNA the same, running back Mark Ingram II said. Its not like its a full rebuild here. We have a team that can make a lot of noise and make a run at it. Obviously, we have to improve and get better and gel as a unit. But I think keeping the DNA of the team, the bloodline of the team, the culture of the team the same is huge.

It helps that everyone -- including offensive players like Ingram -- has seen Allens results on the defensive side of the ball. Under Allens watch, the Saints have ranked fourth in the NFL in both yards allowed and points allowed over the past three seasons. Last December, they became the first team to shut out Tom Brady in 15 years with a 9-0 win on the road against the Tampa Bay Buccaneers.

Although the Saints missed the playoffs at 9-8 in an injury-ravaged 2021 season, their 58 regular-season wins over the past five years rank second in the NFL to only the Kansas City Chiefs.

Even players who just joined the Saints in free agency, like safety Tyrann Mathieu and receiver Jarvis Landry, spoke about being attracted by the established culture in New Orleans -- despite the head coaching change.

The level of consistency is nice. Its something that you rely on. Its something you already trust, defensive end Cameron Jordan said. [Allen is] someone we already trusted. So when you say, Hey, this is for the better of the team, you believe that. Its not like a new guy coming in saying, Hey, this is how were gonna run the team and youre like, Damn, do I buy in or not buy in?

You know what our defense is about, and that immediately brings credibility.

That consistency is felt throughout the coaching staff, where Allen retained longtime offensive coordinator Pete Carmichael Jr. and promoted assistants Nielsen and Kris Richard to the roles of co-defensive coordinator. The biggest staff change the Saints made this offseason was rehiring former Buffalo Bills and Jacksonville Jaguars head coach Doug Marrone as offensive line coach -- after Marrone previously served as Paytons offensive coordinator from 2006 to 2008.

Allen was also part of Paytons original staff from 2006 to 2010, including the Saints Super Bowl-winning 2009 season, before he became the Denver Broncos defensive coordinator in 2011 and Raiders coach in 2012. Allen returned to New Orleans in 2015.

What we do works and what we do is effective. And lets be honest, Dennis has been a part of developing that, said assistant offensive line coach Zach Strief, who was a rookie when Payton and Allen first arrived in 2006. [Allen] has been a big part of building the culture and the structure. So even though Sean was the head coach, some of it might have come out of [Allen's] brain.

The most noticeable change players and coaches pointed out was a slightly enhanced attention to detail. Not that Payton didnt sweat the small stuff -- he absolutely did -- but Allen is approaching everything with fresh eyes, including meeting times and practice drills.

DAs always been about the minutiae, and its been interesting to see him attack with that same idea on the offensive side that everything needs to be exact, said Jordan, who said he has so far resisted the urge to poke fun at Allen for anything -- or even to complain when the now-impartial head coach doesnt credit the defense for enough sacks in practice.

Im just trying not to get on his nerves, said the often-rambunctious Jordan -- who admits he may have some firsthand experience with that.

I will fall in line and say Sir, yes sir ... for the time being.

PROVIDENCE Surely the game-tying home run would be too difficult to come back from.

But it wasnt.

The closer who hadnt thrown a single pitch all year couldnt possibly escape this jam.

But he did.

The North Kingstown High School baseball team has made a habit of meeting every challenge the last two years. Pitching, defense, and timely hitting have been bolstered by an amazing ability to keep fighting. The last two examples were particularly remarkable and they allowed the Skippers to capture their second consecutive state championship with a sweep of Bishop Hendricken this past weekend.

Its team over talent, head coach Kevin Gormley said. Youve got to play the game. These guys, I just told them, theyre the toughest [players] Ive ever coached. Their mental toughness is second to nobody Ive ever coached. A couple of times, they could have folded. They just come back. They dont stop.

It has become a trademark. There was the steady grind required in 2021, when the Skippers were a middle-of-the-road team that caught fire in the postseason and won the state title, with some bumps along the way. They maintained their lofty standards this year, but their quest for a repeat could have ended before it began. They needed a late rally to win their playoff opener. They also fell behind in a semifinal series game. In the finals, they had to scratch and claw to hang on to a 1-0 series-opening win.

The hurdles that popped up in game two of the championship series were the most significant yet, but the Skippers simply upped the ante right along with the stakes. When Hendricken star Brandyn Durand tied the game with a lightning strike of a home run in the bottom of the seventh inning, the Skippers immediately responded with four runs. And when the Hawks loaded the bases with nobody out in the bottom of the eighth, T.J. Gormley went to the mound for the first time all season. The senior stopped the rally in its tracks to seal a 10-7 win.

Its unreal. Im higher than cloud nine right now, T.J. Gormley said. That was such a hard-fought game. That was the hardest game weve played in all year. Im so proud of us. We fought adversity all year. We played a lot of close games. Thats a great team over there. Im so proud of our guys, that we got it done in crunch time.

Before the drama, the Skippers were on the fast track. In game one, Evan Maloney pitched a gem and Braeden Perry closed it out. Perry picked up where he left off as he took the mound for game two, stretching the scoreless streak to 11 innings.

And the Skippers staked him to a lead. After leaving the bases loaded in the first inning, they took advantage of a chance in the second inning. No. 9 hitter Quincy Rome was hit by a pitch with two outs and moved to second on a wild pitch. T.J. Gormley sent him home with an RBI single. Andrew Ciarniello followed with an RBI double and Josh Lincourt kept the line moving with an RBI single. The Skippers led 3-0 and had chased Hendricken starter Ryan Thompson.

North added two more runs in the fifth. Ciarniello walked and Lincourt singled. Maloney reached on an error that allowed Ciarniello to score. A sacrifice fly by Rob Lamond plated Lincourt and made it 5-0.

Perry had worked out of some trouble in the fourth inning thanks to a pair of strikeouts with runners in scoring position. The Hawks broke through in the fifth. A single, two errors and a sacrifice fly pushed two runs across. Then Durand hit the first of his two home runs, a blast to left field that made it a one-run game.

Perry kept North in front with a scoreless sixth inning, working around a leadoff single and stranding the tying run at third. The Skippers picked up an insurance run in the seventh as Max Proulx lined an RBI double to score Maloney.

With Hendricken down to its last three outs, Perry headed back to the mound, looking to finish off a playoff run in which only he and Maloney had thrown a pitch for the Skippers. That was the way the Skippers would have drawn it up and the senior aces came close to delivering, but reality got messy.

Braeden Campbell led off the seventh with a single. Perry retired the next two batters but still had to get through Durand. The University of Kentucy commit and 2021 Gatorade Player of the Year lined a 1-1 pitch to deep right field. It seemed to still be going up when it crested the fence for a game-tying two-run homer.

The title shot was slipping away in jarring fashion.

That was pretty deflating. It has to be, Maloney said. But we know what were made of. We know were going to fight to the very end. We didnt want to come back tomorrow. We wanted the sweep.

The celebration had barely died down when North began delivering its rebuttal. Evan Beattie relieved Perry and struck out Jared Munoz to end the seventh inning and keep the game tied.

Then the Skippers went to work. Gormley reached on an error with one out in the eighth and Ciarniello stayed hot with an RBI triple to deep right field, which quickly broke the tie. After a walk to Lincourt, Maloney plated Ciarniello for the two-run lead. Lamond then reached on a fielders choice. With a first-and-third situation, the Skippers tried some trickery, with Lamond dancing off first base and getting himself into a rundown. Lincourt broke for home and beat the throw. When the ball got away, Lamond headed for third, and when he saw that nobody was covering home, he never stopped running.

Just like that, the Skippers had a 10-6 lead.

Back and forth, crazy game, Ciarniello said. Were a resilient team. We know we handle adversity better than anybody in the state. Even when they scored those runs, had those big innings, we knew we could come back from that. We knew we still had more left, and we showed it in those last few innings.

One more roadblock emerged in the eighth inning. Beattie stayed on the mound and was greeted by three straight hits, the last of which plated a run that made it 10-7. When Beattie walked Alex Clemmey to load the bases, Kevin Gormley made the call to bring in T.J.

He had been a successful closer in 2021 but a shoulder injury suffered during football season last fall led to surgery and kept him from pitching all spring. He and his father had talked about maybe pitching in an emergency.

And here it was.

I was the safety guy, the last resort, T.J. Gormley said.

The first pitch he threw came right back at him. He snagged the chopper and fired home for an out. Lincourt threw to first for a double play. It was one more perfect answer.

Right before I faced him, I said to Josh, Ground ball back to me, I got you, T.J. said. One hopper right there. A lot of pressure was lifted off.

After a walk loaded the bases again, Gormley got Jack LaRose to hit a fly ball to right-center field. Lamond camped under it and squeezed it for the final out. Durand was left in the on-deck circle.

The Skippers celebrated. They are the first public school to win two straight D-I baseball titles since Cranston West in 2006 and 2007.

We had all the confidence in the world, T.J. Gormley said. This was our goal from day one. We were going to be upset if we didnt repeat.

Perhaps it was always going to end like this not necessarily with another title, but with a championship team going down fighting.

Its been like that all year, Gormley said. Weve won a lot of close games this year. Weve never been tested like that. Its the players. We develop players. We dont inherit talent. We develop talent. And theres a difference when you do that, because they believe in one another. Theyve been playing with one another. Theyre working hard. And it shows: That guys got my back, because I see him putting in the effort. Thats what we do. We just work.

Championship DNA powered NK baseball to another title - The Independent

1. The circulating tumour DNA-guided approach was non-inferior to the standard clinicopathological approach in terms of 2-year recurrence-free survival.

2. Less adjuvant chemotherapy was used with the circulating tumour DNA approach.

Evidence Rating Level: 1 (Excellent)

Study Rundown: Cancer recurrence risk after surgery is usually estimated clinicopathologically, whereby adjuvant therapy is recommended if reduction of cancer recurrence has been demonstrated. However, in colorectal cancer stage II, classifications of high and low-risk patients are inadequate since many high-risk patients do not have disease recurrence while some low-risk patients do. This study explored the use of circulating tumour DNA (ctDNA) to predict recurrence risk after surgery of stage II colon cancer patients and accordingly better assess their need for adjuvant chemotherapy. Patients were randomly assigned to have their cancer managed according to their ctDNA results or by the standard clinicopathological criteria. Compared to the standard management group, a lower percentage of patients in the ctDNA group received adjuvant chemotherapy. Reassuringly, the 2-year recurrence-free survival in the ctDNA guided management was non-inferior to standard management. Limitations to this study include the lack of randomization of ctDNA-positive and ctDNA-negative patients in receiving treatment or not. A longer follow up is also needed to determine if chemotherapy in ctDNA-positive patients prevents relapse or simply delays it. The strengths of this study are that it has limited bias given the design and that it provides an accurate alternative to the current clinicopathological management. With this ctDNA approach, certain subgroups can avoid unnecessary chemotherapy, along with the physical and financial costs that that accompany it. Overall, ctDNA is a powerful and useful biomarker that will change the current management of stage II colon cancer and future studies will investigate the role of intensification and de-escalation of treatment based on ctDNA.

Relevant Reading: Adjuvant chemotherapy for stage II colon cancer

In-Depth [randomized control trial]: This phase II multicenter study in Australia randomly assigned 455 patients in a 2:1 ratio to receive ctDNA guided management or standard clinicopathological management of their stage II colon cancer; 302 were in the ctDNA group and 153 in the standard management group. Patients in the ctDNA group who had a positive result receive physicians choice of adjuvant chemotherapy, while the standard treatment proceeded to adjuvant systemic therapy based on standard of care risk stratification criteria. Two-year recurrence-free survival was 93.5% and 92.4% for the ctDNA and standard management groups, respectively (95% confidence interval [CI], -4.1 to 6.2; noninferiority margin, -8.5%). In the ctDNA group, 15% of ctDNA positive patients received adjuvant chemotherapy compared to 28% in the standard management group (relative risk, 1.82%; 95% CI, 1.25 to 2.65). Three-year recurrence-free survival for ctDNA-positive patients who received adjuvant chemotherapy and ctDNA-negative patients who did not was 86.4% and 92.5%, respectively (hazard ratio, 1.83; 95% CI, 0.79 to 4.27). Overall, the ctDNA-guided approach in the treatment of stage II colon cancer reduced adjuvant chemotherapy use while not altering recurrence-free survival.

Circulating Tumour DNA Analysis reduced adjuvant chemotherapy use while not compromising recurrence-free survival in stage II colon cancer -...

Monkeypox is suddenly on everyones radar, having gone from a handful of cases outside of the area where it is endemic to over 1,600 cases in mere weeks. Given the horrors that COVID brought, it is hardly surprising that people are wondering if this is another pandemic in the making.

Monkeypox, despite its name, is more commonly found in rodents and squirrels in west and central Africa. Why, people have asked, is it spreading in areas where there is no natural animal reservoir? Has the virus mutated to become more efficient at spreading from human to human?

Of course, we are all too familiar with variants that SARS-CoV-2 (the virus that causes COVID) has spawned: alpha, beta, gamma, delta, omicron not to mention the sub-variants. So whats to stop a virus that was once more at home in the tropics from adapting to new environments or becoming better at spreading?

A key difference between monkeypox and coronavirus is that the former is a DNA virus and the latter an RNA virus. In short, RNA viruses make more mistakes in their genetic code when replicating than DNA viruses. More mistakes mean more mutations, and hence more chance to come up with a new design that is better (more fit in a Darwinian sense) than the older version that spawned it. (Of course, many new variants are less adapted to their environment and so fizzle out without us even knowing they existed.)

DNA viruses such as monkeypox are more stable. They are able to proof read their genomes, so mistakes (read: variants) are more often spotted. This doesnt mean DNA viruses cant change at all, but that the likelihood of any changes is less than with RNA viruses.

Poxviruses that can infect humans include smallpox (now extinct in the wild thanks to vaccines), cowpox, molluscum contagiosum and monkeypox, but not chickenpox, which is neither a pox virus nor found in chickens. They are a remarkably stable group of viruses that cause characteristic pustules pox being from the Old English pocc meaning pustule, blister or ulcer.

With any virus, particularly those that only infect a few people each year, it is difficult to know the full extent of symptoms. With the increase of cases, we are starting to see what we would term atypical presentations of the virus. This means that people are not displaying the typical pustules covering the entire body. Instead, we are seeing small sores in the areas of contact with infected people.

This atypical presentation is probably not due to significant changes in the virus, as a genetic sequence of the virus from a patient in Portugal did not find significant changes in the virus compared with previous outbreaks in 2018 and 2019. Instead, the atypical presentation is probably because we are seeing many more infections and therefore a wider range of symptoms.

One other possible reason for the change is that the strain (called a clade) of monkeypox (west African) currently circulating in non-endemic countries tends to produce milder infections than the central African strain.

Given what we know about other pox viruses and the stability of DNA viruses, it is likely that the monkeypox virus will be slow to change. This is not the only reason for cautious optimism. We also have a vaccine that is about 85% effective against monkeypox. Regardless of how many people are infected, the vaccine will still be effective, due to the low rate of mutation compared with RNA viruses. In other words, variants that can escape the vaccine are unlikely to emerge.

This vaccine, together with public health measures such as contact tracing, will hopefully be enough to contain this outbreak.

The facility, which is located at 900 S Loop, Ste 170, Houston, Texas will be closed effective June 13, 2022. "Theoptimization of the company's infrastructure and logistics are an essential part of their becoming a more sustainably profitable business and tobetter meet the needs of the customers," commented Ms. Emylee Thai, Founder of Artemis DNA.

Artemis DNA has been growing at a rapid pace since it inception in 2019, and despite the announcement of the Houston facility closure, the firm continues to grow strategically, including a recent international expansion into the Vietnammarket and expanding the firm'sin-depth oncology portfolio:

Vietnam was also chosen to be the first country for Artemis DNA's global expansion because of the Founder's tribute to her Vietnamese father and mother, who both passed away from cancer.

Alcohol use disorder is associated with DNA methylation-based shortening of telomere length and regulated by TESPA1: implications for aging |...

A St. Paul man has been charged after DNA from a left-behind item linked him to a gas station robbery.

Christian Allan Gorr, 22, is charged via warrant with first-degree aggravated robbery. He was not yet in custody as of Tuesday morning.

A criminal complaint states law enforcement was called to investigate a robbery at a gas station in St. Paul at around 5:30 p.m. on Nov. 21, 2021. The suspect was wearing black clothing and an Aeropostale sweatshirt while carrying a revolver and a black bag.

About an hour later, authorities learned a Super USA gas station in Inver Grove Heights was robbed at gunpoint by a person with the same description.

The complaint states the suspect left behind a bag at the St. Paul robbery, and the bag contained a white surgical mask and a pair of gloves. When the items were sent to the Minnesota Bureau of Criminal Apprehension for DNA testing, the results matched the profile of Gorr and his brother, who was in Nashville at the time.

According to the complaint, Gorr is a suspect in several other robberies in the east metro that are similar in nature. However, he currently faces just one count of aggravated robbery.

With a conviction, first-degree aggravated robbery carries a maximum penalty of 20 years in prison and a $35,000 fine.
