Perez represented himself as an Apostolic pastor and bishop at Iglesia Antigua, a church that rented space at St. George's Episcopalian Church in Laguna Hills. Perez met his five victims through the church and gained their trust by befriending their families and having the boys assist with church services.
According to the Orange County District Attorney’s (OCDA) office, between 2007 and 2011, Perez sexually assaulted the five victims between the ages of 9 and 15 years old on one or more occasions while they were visiting or sleeping over at the defendant's apartment.
Sometime after the sexual assault of John Doe #1 in 2011, the victim told his mother about the abuse and she reported it to the Orange County Sheriff's Department (OCSD), who investigated this case. The subsequent investigation led to the discovery of John Doe #2.
The defendant was arrested and charged for the first two victims in September 2011. Based on continued investigation and media coverage, OCSD discovered John Does #3, #4, and #5, and Perez was charged by the Orange County District Attorney's Office for the additional sex crimes in January 2012.
