FRENCH CAMP, Calif. (AP) -- San Joaquin County authorities are investigating the death of a 16-year-old boy who was found unresponsive after escaping from a juvenile detention facility near Stockton.

Officials say Tracy Brown Jr. was found in a field near the Camp Peterson facility in French Camp on Thursday night. He was taken to a hospital where he was pronounced dead.
