TUCSON, Ariz. -- Authorities said at least three of five sets of skeletal remains found concealed in the desert west of Tucson show signs of gunshot wounds.
Border Patrol agents found the remains on May 28 about 12 miles northwest of Sells on the Tohono O'odham Reservation in an area often used by smugglers.
Pima County's chief deputy medical examiner -- Dr. Greg Hess -- said the bodies had been in the desert between six months and a year.
Hess has already concluded that all five were homicide victims and all are men.
The Arizona Daily Star reported that Hess is trying to determine the type of injuries suffered by the other two victims.
Hess said none of the remains have been identified.
