Patrol Officer Glenn Raye Miles, a 42-year-old member of the Tohono O'odham Nation, was killed in the line of duty on February 21, 1986. Miles had 15 years in law enforcement, including five years with the United States Customs Service and about a decade with the Tohono O'odham National Police Department. He radioed dispatch that day reporting a pursuit of three individuals near the San Miguel border gate on the Tohono O'odham Indian Reservation, near Sells, Arizona.

Fellow officers found him about one mile north of the gate; he had sustained multiple gunshot wounds and his service weapon remained with him. The three people he reported pursuing had disappeared from the scene. An extensive investigation was conducted, but no suspects were ever publicly identified or arrested and the case later went cold.

Officer Miles left behind a wife and son and is remembered by the law enforcement community he served. Did anyone in the area at the time see or hear anything that could still help resolve this case?
