Police say Oscar Mayorga, 21, assaulted a woman during the twilight hours of March 26, 2006, near the intersection of Phyllis Avenue and Pamela Drive. Police believe he came up behind the woman, put his arm around her, and threatened her with a handgun. He then pulled her into a dark secluded area where he violently assaulted and then robbed her.
Following the attack, the woman called the police from a neighbor's house and then sought aid at a local hospital. Because the assault was reported immediately, medical personnel and detectives on the scene were able to gather concrete forensic evidence for a "sexual assault kit," helping them use DNA evidence to find a match.
The Santa Clara County Crime Laboratory identified Mayorga as a suspect after lab analysis linked him to the crime. Mayorga is already serving a sentence at Jamestown State Prison, located in the California foothills, for an unrelated felony conviction.
He is now charged with forcible rape, two counts of penetration with a foreign object, and other crimes. His arraignment in Santa Clara County Superior Court has not yet been scheduled.
