CONTRA COSTA COUNTY, CA — The Contra Costa County District Attorney's Office was asked to prosecute more cases in 2025 than the prior year for the fourth year in a row, according to an annual report released this week.

District Attorney Diana Becton received nearly 21,000 requests for prosecutions, more than any other year since 2018, when she was elected. Felony cases requested by law enforcement also reached a near-high for that period and jumped by about 8% from 2024, with a total of 5,440 felony prosecutions requested in 2025.

The annual report released Tuesday summarized cases brought and convictions won by the District Attorney's Office last year, including the convictions of five Pittsburg and Antioch police officers who were charged in 2023 with bribery and criminal conspiracy for canceling traffic tickets in exchange for personal benefits.

A joint investigation involving the District Attorney's Office and the FBI that began in 2022 also uncovered racist, homophobic and sexist messages on officers' phones. All five officers — Timothy Manly Williams, Calvin Prieto, Adrea Rodriguez, Ben Padilla, and Jean Earnesto Mejia-Orozco — ultimately accepted guilty plea deals.

Some lost their law enforcement certifications, according to Becton's office. Becton said public corruption cases are challenging to bring but are necessary to build public trust. "While public corruption cases can be difficult for the affected communities, holding officials accountable ultimately preserves the integrity of our government and helps reinforce the community's faith in justice -- which is essential to a functioning democracy," Becton wrote in the report.

The report highlighted high conviction rates for the Contra Costa County District Attorney's Office compared to the state average, with Becton and her prosecutors convincing juries in 25 out of 26 felony cases to return guilty verdicts.

That conviction rate of 96% beats the statewide average by about 15 percentage points, according to the report. Becton filed 27 of the 30 murder cases recommended by law enforcement for trials. Out of 15 homicide cases that ended in 2025, 14 people were found guilty, including 12 who were convicted of murder.

The two others were found guilty of manslaughter. Two of those homicide convictions involved cold cases, including the second-degree murder conviction of James Grimsley, a truck driver who was found guilty of killing 28-year-old Terrie Ladwig, a transgender woman from Concord whose death in 1994 went unresolved until last August's guilty verdict. Grimsley was identified as the killer through advanced DNA techniques.

He was sentenced to life in prison with eligibility for parole in 2040. The other dormant homicide case resolved was the shooting death of a Pittsburg man, Larry Abercrombie Sr., in 2007. Desante Blake pleaded guilty to manslaughter and attempted robbery after DNA evidence allegedly linked him to the crime. The report's cold case section also noted a no contest plea for a 2015 San Ramon kidnapping by Matthew Muller, a man who was previously convicted for a notorious kidnapping and rape of a woman from her home in Vallejo in 2015.

The victim escaped but her reports to the Vallejo Police Department were doubted, before Muller was arrested for another attempted kidnapping and her story was proven true upon his confession. The crime was the subject of a Netflix docuseries in 2024 called "American Nightmare." Muller was serving a life sentence for the previous crimes when he confessed to the San Ramon kidnapping-for-ransom.

The District Attorney's Office also expanded services and operations in 2025 by opening a new branch location in Pittsburg with 30 attorneys and staff and hiring a new therapy dog, Fenner. The black Labrador was paired with Bear, the office's other therapy dog, to provide comfort to crime victims, particularly children.

The report also highlighted success in the District Attorney's Office's Neighborhood Restorative Partnership program, which focuses on building relationships between law enforcement and residents and finding remedies to low-level offenses through community solutions.

The program brings together offenders, victims, and community members to find ways to achieve justice without going through the criminal justice system. The report said 119 people had completed the program since 2022 and only one person reoffended, a recidivism rate of less than 1%. The state average for misdemeanor recidivism is about 21%.
