A former Stafford County School Board member and teacher was charged Monday with sexually assaulting four young girls in the 1990s.

A grand jury charged Thomas F. Villacres, 53, with 111 counts, including aggravated sexual battery and indecent liberties with a minor while in a supervisory role.

The children ranged in age from 6 to 10 at the time of the alleged assaults, which took place between 1990 and 1998, according to Bill Kennedy, a spokesman for the county sheriff’s department.

Villacres taught in a Stafford County high school in 1994 and 1995, according to a school district spokeswoman. He served on the county School Board from 1998 to 2005, and served as chairman of the Virginia School Boards Association and president of an elementary school parent-teacher organization.

Kennedy said that Villacres’s work in the school district was not part of the police investigation. “That, to be candid, was not germane to our investigation, what his job was,” he said. To protect the victims’ privacy, he would not say whether the girls were Villacres’s students.

Kennedy said that the allegations of sexual abuse came to light when Villacres, who moved from Stafford County to Florida and was working for the Defense Intelligence Agency there, underwent a routine federal background check. DIA investigators learned of information that made them suspect that he had been a perpetrator of sexual abuse, and alerted the Stafford County sheriff’s department, authorities said.

The sheriff’s department asks that any other people who believe they were victims contact Detective Pat Tudor at 540-658-4450.

Villacres was arrested by Brevard County police in Florida on Monday and is in the process of being extradited to Virginia.
