Political lean describes where an outlet sits within the politics of its own country. It is never a position on a single global scale.
Political lean is comparable inside one country and not across them, which is why the bar groups by country first. Publicly funded broadcasters are not marked as state-linked.
The owner of each outlet is listed as a matter of record, not as a judgement about the outlet.
Every outlet covering this story shares the same political lean; read with that in mind.
A judge in Golden, Colorado, sentenced former Colorado Bureau of Investigation forensic analyst Yvonne “Missy” Woods to 10 years in prison on Tuesday. Woods pleaded guilty in June to charges of perjury, forgery, committing a cybercrime, and attempting to influence a public servant. Dozens of other counts were dismissed as part of a plea agreement.
Authorities stated that Woods manipulated DNA data in cases involving robbery, sexual assault, homicide, and other crimes, which raised questions about the validity of hundreds of criminal cases. The misconduct led to the review of hundreds of cases and the vacation of at least one murder conviction. Michael Clark was released from prison in 2025 after his lawyers argued that Woods mishandled DNA evidence, although prosecutors indicated they intend to retry him.
Woods resigned in 2023 following a career spanning several decades. She was accused of deleting data to hide failures in the testing process, altering data to conceal tampering, and failing to document tests in case records. According to an arrest affidavit, Woods told investigators she changed data to complete cases more quickly. During her sentencing, Woods apologized, stating that she failed the responsibility entrusted to her.
The investigation began in September 2023 after an intern discovered missing information in a 2018 case. However, a 2024 internal affairs report revealed that concerns about her work surfaced as early as 2014, and she was temporarily removed from DNA cases in 2018 due to data manipulation accusations. State officials estimated that the response to her actions could cost more than $11 million.
In two homicide cases, defendants received lesser sentences through plea deals because prosecutors feared Woods' involvement would lead to acquittals. Other convictions across Colorado have been challenged in court. Colorado Bureau of Investigation Director Armando Saldate stated that the organization is seeking to reform its laboratories to rebuild public trust, noting that the actions of one individual do not define the organization.
