A former D.C. police officer is accused of sexually assaulting nearly a dozen women across the D.C. area. Timothy Valentin is accused of drugging and assaulting women he met on dating apps. So far, police say they've identified victims in Alexandria, Prince George's County and Takoma Park. Valentin left the Metropolitan Police Department in 2022. He's accused of assaults in 2024 and 2025. In at least one case, investigators say he told a victim he was in law enforcement, and police found a gun and badge in his car. News4 found disturbing details in Alexandria court documents filed in connection with his arrest in December. Detectives found dozens of explicit videos on his cellphone. "I want to acknowledge the enormity of this moment," Alexandria Chief of Police Tarrick McGuire said at a news conference Monday. Valentin faces charges related to four victims in Alexandria.
