VANCOUVER, Wash. (AP) — Officials say a police dog tracked down an escaped Clark County inmate who buried himself in sand.

Clark County Sheriff's Office spokesman Sgt. Dave Nelson says police dog Apollo tracked 44-year-old Cory Cunningham after he climbed over the Clark County Jail's work center fence in Vancouver, Washington Thursday afternoon.

Nelson says Apollo and a Clark County sheriff's deputy tracked Cunningham for 45 minutes before finding him nearby.

Nelson says Cunningham had completely buried himself in sand under some bushes.

Cunningham was taken to a hospital for treatment, then back to jail, where he faces escape charges.
