A former San Francisco Sheriff’s deputy was charged with sexually assaulting a transgender woman in one of the downtown San Francisco jails, prosecutors said Friday. Damon Jones, 34, was accused of engaging in sexual activity with a confined adult while acting as a peace officer employed in a p ublic detention facility and dissuading a witness from reporting a crime, the San Francisco District Attorney’s Office said. Both are felonies. San Francisco has several county jail facilities. The major housing units are in San Bruno; others are downtown at the Hall of Justice and at 425 7th St., where Jones was assigned, which houses women and a gender-responsive rehabilitation program. Prosecutors said Jones told the transgender woman to go to the gym with him on Sept. 11, 2025. Video surveillance showed Jones walking into a bathroom stall with the victim following him inside. There, she told investigators, he had her perform oral sex on him. Video showed the woman coming out of the bathroom and reaching into her sock, pulling out a plastic bag and spitting into it. The woman told investigators she saved some of the ejaculate in her mouth, which is what she spat into the bag. She gave the bag to her attorney, who took it to a crime lab. DNA testing came back with a match to Jones, prosecutor said. “The victim also told detectives that after the oral copulation, Mr. Jones told her to shut up, that no one would believe her, and not to tell anyone or he ‘would roll her up to F Pod,’ which the victim understood was a threat to transfer her to a unit where she would feel less safe,” according to the District Attorney’s Office. The Sheriff’s Office said Jones was hired as a deputy in June 2024. He was assigned to County Jail 2, where the assault allegedly occurred, in August 2025. Anyone with information regarding the case is asked to call the San Francisco Police Department Tip Line at 415-575-4444 or send a text to TIP411 and begin the message with SFPD. ...read more read less
