Antioch Police Department & Pittsburg Police Department Offenses
In August 2023, the Contra Costa County District Attorney’s Office charged five law enforcement officers from the Antioch and Pittsburg Police Departments with criminal offenses. This was a major step in our effort to fight public corruption and reinforce the integrity of our justice system. The cases were the result of a long investigation with the FBI that started in March 2022. They show our office’s commitment to holding public officials accountable, no matter their position or status. The officers were charged with taking part in a criminal conspiracy.
All six cases against Timothy Manly Williams, Calvin Prieto, Adrea Rodriguez, Ben Padilla, and Jean Earnesto Mejia-Orozco ended in guilty pleas. The officers also faced administrative hearings with the City of Antioch, and some lost their law enforcement certifications as a result of their criminal convictions.
“Prosecuting public servants for corruption is never easy, but accountability is essential to maintaining public trust,” said District Attorney Diana Becton. “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.”
