PHOENIX -- The 37-year-old daughter of the owner of D.W. Higgins Charter School was arrested on Thursday and booked on two counts of sexual conduct with a minor, deputies said.

In late January 2006, Maricopa County sheriff's detectives said they learned that a sex crime had occurred between Judith Wallace and a 15-year-old male victim.

The Sheriff's Office Special Victims Unit said they learned during the investigation that the victim had allegedly engaged in a sexual relationship with Wallace and that she had given him alcohol.

The victim also reported that Wallace would frequently take him to parties and social gatherings as a "couple," detectives said.

A witness told detectives that it was common to see the two together outside of school and at other staff members' homes, according to deputies.

The victim, now 16, stated he and Wallace engaged in sexual acts on separate occasions between February 2006 and April 2006.

"This conduct is inexcusable and will not be tolerated," Sheriff Joe Arpaio said. "No child should be victimized, especially by someone in a position of trust."

Wallace was arrested at her home in Chandler and booked into the Fourth Avenue Jail.
