DA will dismiss cases involving fired detective
ANTIOCH (AP) — Prosecutors will move to dismiss three cases potentially tainted by the testimony of a former Antioch detective who was fired in 2017 for leaking information to known criminals, Contra Costa County District Attorney Diana Becton announced Thursday.
Former Antioch Detective Santiago Castillo’s misconduct was exposed through records obtained by news organizations that are part of the California Reporting Project, which is collecting officer misconduct and serious use-of-force information throughout the state under a new police transparency law.
The records show Castillo was suspected of sharing confidential information with suspected criminals as far back as 2010, KQED News reported. When internal affairs investigators confronted Castillo, they found his explanation, that he sometimes told informants police were watching them “to scare them,” was not credible. Investigators also found Castillo had submitted overtime that he didn’t work and had mishandled evidence.
