A former forensic analyst with the Colorado Bureau of Investigation pleaded guilty Tuesday to four felony counts stemming from accusations that she manipulated and omitted data to speed up the DNA testing process, calling into question the validity of hundreds of criminal cases.

Yvonne "Missy" Woods entered guilty pleas to committing a cybercrime, perjury, attempting to influence a public servant and forgery. Dozens of other counts were dismissed as part of a plea agreement.

Woods was set to stand trial later this year. Instead, she'll face between 8 and 16 years in prison when she's sentenced in September.

Woods and her attorneys declined to talk to reporters after Tuesday's hearing.

Authorities accused Woods, who resigned in 2023 after a decades-long career, of altering data to conceal tampering, deleting data that showed she failed to troubleshoot issues within the testing process and not thoroughly documenting tests performed in case records.

The investigation into Woods' misconduct began in September 2023 after an intern at the bureau discovered missing information in a case that Woods handled in 2018. According to an arrest affidavit, Woods allegedly told investigators at one point that she had changed data to complete cases more quickly.

Problems with the scientist's work were found in cases involving homicide, sexual assault, robbery and other crimes, according to a law enforcement affidavit. Prosecutors were forced to review hundreds of cases.

At least one murder conviction was overturned as a result of Woods' misconduct. Michael Clark was released from prison in 2025 after his lawyers argued that DNA evidence in the case was mishandled by Woods, but prosecutors are seeking to retry him.

In at least two cases, both homicides, the defendants received lesser sentences under plea deals than they could have faced if they went to trial because prosecutors were afraid Woods' involvement could lead to acquittals. Convictions in other cases also are being challenged in courts across Colorado.

State officials have said that the response to Woods' actions could end up costing more than $11 million.

The state investigation bureau in a statement issued Tuesday described Woods' actions as intentional criminal fraud and said it didn't reflect the bureau's practices.

"This moment is not about moving on, for CBI it's about moving forward," said Armando Saldate, bureau director. "Today's guilty plea is an important moment of accountability."

The bureau said it has been making changes and is committed to following best practices used nationwide in forensic science.

A Texas teenager who fatally stabbed a 17-year-old track athlete from a rival team during a high school meet was convicted of murder and sentenced to 35 years in prison Tuesday in a case that drew wide attention beyond the booming Dallas suburb where they were students.

A jury rejected Karmelo Anthony's claims of self-defense during a confrontation with Austin Metcalf in stadium bleachers last year. Most people who testified were students who described a heated exchange over Anthony's refusal on a rainy spring day to leave a tent that belonged to Metcalf's team.

Anthony, now 19, did not testify at trial and only his mother took the stand during the sentencing phase, telling jurors her son was sorry.

Notoriety about the case spread, in part, because of a flood of social media posts that amplified the killing in racial terms. Anthony is Black; Metcalf was white. Lawyers on both sides, however, told jurors the tragedy had nothing to do with race.

Jeff Metcalf, Austin's father, had also denounced those who sought to stoke racial divisions after his son was killed. A year later, he said again in a Collin County courtroom that it was never about race while his voice swelled with anger over the death of his son.

"You failed your parents, you failed yourself and you failed society," said Metcalf, looking at Anthony after the teenager was sentenced.

Jurors, who deliberated for less than three hours, had the option of a lesser charge, manslaughter, but didn't choose it.

Prosecutor Bill Wirskye had asked for a lengthy prison term.

"Mercy to the guilty," he said, "is cruelty to the innocent."

Earlier Tuesday, during the trial's closing arguments, the jury heard dueling narratives from Wirskye and defense attorney Mike Howard about what happened in April 2025.

Several schools were competing when Anthony sat under the Memorial High School tent that was perched in the bleachers. Austin Metcalf and others had repeatedly told Anthony to leave, witnesses testified, leading to an escalating confrontation.

Howard told jurors that Metcalf had "no legal right to put his hands on Karmelo."

"Texas law does not require that you wait until you get hit," Howard said. "In that split second of chaos, you must put yourself in his shoes."

During the nearly weeklong trial, prosecutors said Anthony provoked Metcalf, and witnesses testified that Anthony was the aggressor.

"This is not self-defense, folks. It's murder plain and simple," Wirskye said.

Anthony at one point reached inside a bag and replied: "Touch me and see what happens," according to a police report.

Metcalf pushed Anthony, according to witnesses, who said Anthony then pulled out a knife and stabbed him in the chest.

"You don't get to meet a shove with a stab, especially if you provoke the shove," Wirskye said.

The teens, both from Frisco, didn't know each other.

"He's very sorry for what he did. Please, have mercy on my son," Anthony's mother, Kala Hayes, pleaded to jurors shortly after the verdict.

The trial drew lines of spectators hoping to find seats in the gallery and unfolded amid heavy security at the Collin County courthouse. As police officers watched Tuesday, dozens of people stood outside the courthouse in 90 degree Fahrenheit heat (32 degrees Celsius) to await the verdict. There were wails of grief from one woman — "This isn't real!" — when the result became known.

Frisco is one of Texas' fastest-growing cities and is dotted with dozens of modern school campuses and gleaming athletic facilities. The parents of Anthony and Metcalf have said they were good students who planned to go to college.

Several students testified that Metcalf, after ordering Anthony to leave his team's tent, scoffed before Anthony reached into a bag and pulled out a knife.

The Supreme Court sided with the Trump administration Thursday in upholding the power of federal regulators to enforce data privacy laws on telecommunications companies.

The 8-1 decision preserved one of the Federal Communications Commission's key tools, though the companies also won a concession from the Republican administration that could shift the regulatory landscape.

The appeal from telecommunications giants Verizon and AT&T challenged a combined $100 million in penalties imposed after the agency determined that the companies had failed to safeguard customer location data.

The companies argued that the FCC's process was unconstitutional because it gave them little opportunity to tell their side of the story in front of a jury.

The administration defended the fines as an essential regulatory tool. But the government also said companies did not have to pay the penalties right away, a regulatory shift in the companies' favor.

The Supreme Court agreed, affirming the FCC's power to order fines when challenges are still available.

"The orders at issue did not settle the carriers' legal obligations because, stated simply, they did not create an obligation to pay," Chief Justice John Roberts wrote for the majority.

Justice Clarence Thomas, the lone dissenter, said he would have given the two telecom companies a clearer path to recouping the fines they already paid.

Other agencies use similar enforcement methods, so a sweeping victory for AT&T and Verizon could have had widespread effects, advocates said.

The environmental group Earthjustice applauded the ruling, saying it has direct implications for other agencies and a key energy-efficiency case.

"By rejecting this unsupported attack on agency authority, the Court's decision safeguards the government's ability to enforce laws that protect people, communities, and the environment," said Caroline Flynn, the group's Supreme Court counsel.

The libertarian-leaning New Civil Liberties Alliance was disappointed by the decision, but expected it to help other companies in the future. "In fact, it may even buttress their willingness to challenge future agency orders in federal court before paying any penalties," said the alliance's president, Mark Chenoweth.

A few more carriers may decide to litigate, but the decision leaves the FCC with the power to "publicly announce large fines with much fanfare," said Doug Orvis, a veteran telecom attorney. "It will be interesting to see what happens going forward."

The Supreme Court's conservative majority has sided against federal agencies and limited their power before. That includes overturning a decades-old decision that had given regulators an advantage in court and stripping another agency of a major tool in fighting securities fraud.

A Canadian man facing murder charges for allegedly selling lethal substances online to people at risk of self-harm has agreed to plead guilty to 14 counts of counseling or aiding suicide, his lawyer said on Saturday.

In turn, Canadian prosecutors will withdraw all 14 murder charges filed against Kenneth Law, lawyer Matthew Gourlay told The Associated Press in a email.

"The plea will be to the charges of aiding suicide," he said in an email. The Canadian Broadcasting Corporation first reported the plea.

Law will make a virtual appearance by Zoom before a Newmarket, Ontario, court on Monday afternoon for the purpose of further scheduling, Gourlay said. The plea and the sentencing will take place at a later date.

Calls to Ontario's Ministry of the Attorney General weren't immediately answered.

Canadian police say Law, from the Toronto area, used a series of websites to market and sell sodium nitrite, a substance commonly used to cure meats that can be deadly if ingested. They say he is suspected of sending at least 1,200 packages to more than 40 countries.

Authorities in the United States, Britain, Italy, Australia and New Zealand also have launched investigations.

It is against the law in Canada for someone to recommend suicide, although assisted suicide has been legal since 2016 for people aged at least 18. Any adult with a serious illness, disease or disability may seek help in dying, but they must ask for assistance from a physician.

Law has been in custody since his arrest at his Mississauga, Ontario, home in May 2023.

According to the Canadian Criminal Code, abetting suicide carries a maximum sentence of 14 years. A murder conviction automatically means life in prison, with no chance of parole for at least 25 years.
