SAN ANTONIO – A sex offender released from prison earlier this year is once again facing charges for allegedly sexually assaulting a 6-year-old child, and there could be more victims, according to Bexar County Sheriff Javier Salazar.
Mark Adrian Guilbeau, 40, was arrested Wednesday night. He’s charged with aggravated sexual assault of a child and violation of sex offender registry.
Guilbeau was arrested with his sister, 32-year-old Delanee Broussard, who is charged with tampering with a witness.
Salazar said Guilbeau was released from prison in January after having served a 10-year sentence from a conviction in 2013 in which a 10-year-old girl was sexually assaulted.
The suspect was arrested after a 6-year-old boy made an outcry that he had been sexually assaulted by a 12-year-old, BCSO said.
After ChildSafe investigators interviewed the child, he told them Guilbeau had sexually abused him.
Salazar said Broussard had instructed the child not to tell investigators that Guilbeau had sexually assaulted him.
Investigators also discovered that Guilbeau lied about his address, where he had access to children, according to Salazar. The sheriff said Guilbeau was not allowed to be near children as a condition of his release.
Salazar said there could be upwards of eight victims who had been sexually assaulted before Guilbeau’s 2013 conviction, and there could be more victims that he targeted after his release.
BCSO is investigating those cases and working to find any other possible victims. Anyone with information about this case or any related to Guilbeau is asked to call 210-335-6000 or email BCSOtips@bexar.org.
