A man charged with repeatedly sexually assaulting his daughter's young friend over a three-year period in his South San Francisco home was found guilty of all charges by a San Mateo County Superior Court jury Thursday, according to prosecutors.
The jury found Ronald Somoza Lauron, now 45, guilty of 28 counts related to the assaults, including forcible sexual penetration, unlawful sex with a minor and dissuading a witness.
The abuse started in August of 2011, when the victim, then in 8th grade, would routinely visit Lauron's home to have sleepovers with his daughter, according to the San Mateo County District Attorney's Office.
The sleepovers happened weekly when the victim was in the 9th and 10th grades, according to prosecutors.
The abuse included masturbation, digital penetration, oral copulation and sexual intercourse, prosecutors said.
After the 10th grade, the victim stopped going to Lauron's home to visit his daughter and, several months later, she reported the abuse to a school counselor who informed her parents.
Lauron, who was arrested in October of 2014, had been out of jail on $750,000 bail but was taken into custody after the guilty verdict was delivered.
