Juan Carlos Pena is a high-risk sex offender and is required to register annually for life. He has a lengthy criminal history dating back to 1982. In 1987, while on parole for a Burglary of a Habitation conviction, he and an associate were involved in the nighttime burglary, aggravated robbery, and sexual assault of a 56-year-old female in McAllen, Texas. He was arrested and sentenced to 50 years in prison. He was paroled in 2005 but violated his parole requirements in 2006. He also failed to meet sex offender registration requirements and was listed as absconded. On October 27, 2006, the Texas Board of Pardons and Paroles issued a warrant for PENA's arrest for Parole Violation (Original Offenses: Burglary and Aggravated Robbery). On December 12, 2006, the Harris County Sheriff's Office issued a warrant for Failure to Register as a Sex Offender.
