Authorities say 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 -- says the bodies had been in the desert for between six months and a year.
Hess has already concluded that all five were homicide victims and all are men.
The Arizona Daily Star says Hess is trying to determine the type of injuries suffered by the other two victims but suspects it'll also be gunshot wounds.
Hess says none of the five remains have been identified.
