CROSSVILLE, Tenn. (AP) _ More than 30 teenagers have fled the custody of the Tennessee Department of Children's Services school for troubled boys in Crossville over the last three years.

WSMV-TV in Nashville reported officials are still searching for two of them.

Crossville Police Maj. Terry White says the multiple escapes tie up the time of officers, who have to drop other duties to look for the juveniles.

The facility is minimum security with no fence and no guards around the yard.

The Upper Cumberland Human Resources Agency runs the school and says it's not a locked-down facility and can only encourage the teens not to runaway.

DCS spokesman Rob Johnson says the state is doing what it can to help find the missing teenagers.
