JEFFERSON COUNTY, Colo. — A former substitute teacher for Jefferson County Public Schools has been arrested for suspicion of sexual assault on a child, the Jefferson County Sheriff’s Office said.

Matthew Lonie, 35, is being held at the Jefferson County Jail.

An arrest affidavit said Lonie admitted to police that he inappropriately touched an underage girl several times beginning in March. He is being held on suspicion of sexual assault by a person of trust and the sheriff’s office said the victim is a family member.

Jefferson County Public Schools said in a statement that Lonie’s last active working day was April 24 and that he “came into contact with his alleged victim outside of his role as a substitute teacher.”

The school district said Lonie worked as a substitute teacher from Nov. 7, 2013 to May 25, 2014, then was rehired in August 2014.

“There were no allegations made of inappropriate behavior with Jeffco students throughout the course of his employment in Jeffco Schools,” the district said.
