SAN FRANCISCO - Today, District Attorney George Gascón announced that a jury found Roberto DeTrinidad, 30, of San Francisco, guilty of assault with intent to commit rape, sodomy, oral copulation, or sexual penetration during the commission of a residential burglary yesterday afternoon.  Mr. DeTrinidad faces life in prison.


“This victim had an incredibly traumatic experience,” said District Attorney George Gascón.  “Her courage to come forward ensures this dangerous predator can’t harm others.”


According to court records, on August 8, 2013, the victim came home after work and fell asleep watching TV.  The victim awoke to pressure and pain on her backside, and noticed a substance that felt like semen on her posterior.  She saw a man walk out of her room and she screamed.  Her roommate woke up and looked for the intruder without success.


A few days later the victim called police. Officers responded and took samples from her bedding which had stains consistent with semen. DNA analysis confirmed a single source profile which matched the Defendant’s.


“These cases are difficult for victims and a challenge for investigators,” said Assistant District Attorney Brad Allred.  “Everyone worked together to ensure justice was served and that a violent man was taken off the streets.” 


A sentencing date for Mr. DeTrinidad has not yet been set.  The Honorable Ethan Schulman presided.  This successful prosecution is due to the excellent work of SFPD Inspectors Rodney Chan and Paul Doherty, District Attorney Investigator Molly Braun, Paralegal Nina Stellini, Victim Advocates Patricia Barragan and Delia Montiel, Post Bar Fellow Erika Maskal, IT Support Staff Morris Moore and Assistant District Attorney Lili Nguyen.  Assistant District Attorney Brad Allred prosecuted the case.
