SANTA CRUZ -- A local youth coach and child welfare advocate was rearrested Friday on suspicion of child molestation after allegedly abusing two minors he worked with as a court appointed special advocate, the Santa Cruz County Sheriff's Office said.

Brian Criswell, 39, of Santa Cruz was arrested Oct. 4 on suspicion of child molestation after an initial investigation by sheriff's investigators, deputy Ryan Kennedy said.

Criswell posted $50,000 bail Oct. 8 but was rearrested Friday after a follow-up investigation revealed an additional victim, allegedly molested during a two-year period between 2009 and 2011, Kennedy said.

Criswell was a volunteer wrestling coach at Harbor High School until early October when he resigned in light of the investigation.

He was also an advocate for children at Court Appointed Special Advocates of Santa Cruz County. The organization trains volunteers to be advocates for abused or neglected children who have become dependents of the county. The advocates are supposed to ensure the child's needs are met.

"We're all very deeply saddened by allegations such as these," said Cynthia Druley, executive director for Court Appointed Special Advocates of Santa Cruz County. "We think that anybody who would harm a child or take part in this kind of criminal behavior has no business being near children, let alone volunteering for a child advocacy organization."

The nonprofit has roughly 130 advocates working with children. This is the first time something like this has happened in the organization's 21-year history, Druley said.

Advocates undergo a thorough background check and an interview with officials.

"We have and will continue to do everything possible to really discover the truth in this matter," Druley said. "We're thankful that the sheriff is working diligently to determine the facts in this case."

While working as a wrestling coach at Branciforte Middle School during 2012-2013, there were no reports against Criswell, Santa Cruz City Schools Superintendent Gary Bloom said.

Bloom added that criminal background checks are done for coaches as well.

Investigators believe there are additional victims and are asking anyone with information to call 831-454-2311.

Criswell is being held in lieu of $500,000 bail and is scheduled to appear in court Oct. 23 for further arraignment.
