Prosecutors say Baca met the victims while working as their intramural sports coach for football, lacrosse and basketball in South Orange County. Baca befriended the families of the victims and groomed the boys by spending time with them, attending their sporting events that he was not coaching, buying them baseball cards and inviting them to his home for meals and to do various work around the house.
In December 2008, one of the victims informed his family of the sexual assault. Orange County Sheriff's investigators went on to identify two other victims.
During a search of Baca's home, investigators found over 2,000 pornographic images of young children being raped. In Baca's computer, they found over 500 child pornography videos and more than 50 written stories describing adult men, including coaches and babysitters, having sex with young boys.
Baca is scheduled to be sentenced on September 17. He faces a maximum sentence of 145 to life in state prison.
