Hundreds of students were on campus and a scrimmage game was taking place on the field around the time of the arrest. The school campus was put on a soft lockdown.
A neighbor said he was at a dance recital on the campus with his family.
"We were in the performance and all of the sudden there's going to be a delay in the performance because they're on a lockdown," said William Garcia. "All we thought is that there's a streaker on the campus."
Sharp was arrested on suspicion of murder and held without bail. Arraignment is scheduled for Monday. It was not immediately clear whether he has an attorney.
The county district attorney's office confirmed the suspect is the son of Calvin Sharp, 45, who was convicted in the August 2007 stabbing death of a 6-year-old child. A meat cleaver was used to kill the child before Calvin Sharp stabbed the boy's mother and a neighbor, according to prosecutors.
Both women survived.
Calvin Sharp tried to plead insanity, but was later found legally sane. He was sentenced to life in prison with parole in December 2012. He remains in custody at California State Prison, Sacramento, according to the California Department of Corrections and Rehabilitation.
Anyone with information about the Thursday assault was asked to call investigators at 805-384-4725.
