A man's decapitated body was found on the side of a dirt road Friday morning west of the Tucson Mountains.

The hands and feet also had also been removed from the body discovered in the 2300 block of North Reservation Road and West Mile Wide Road. None of the missing body parts were found at the scene, Pima County sheriff's Bureau Chief Rick Kastigar said.

The body was discovered by two men cutting grass along the road to feed their animals, he said.

The men flagged down Bureau of Land Management Rangers and border patrol agents in the area, but were released before deputies could question them, Kastigar said.

"We don't know who they are or where they came from," Kastigar said of pair who reported the discovery. "We don't know their association to the crime."

Other evidence was found at the scene but Kastigar could not provide details, citing the ongoing investigation.

Kastigar said that neither he nor the department's veteran investigators have dealt with a case like this before.

"I can tell you that the crime of murder is not necessarily new to that part of the county," Kastigar said. Homicide victims have been found in the remote area.

An autopsy is scheduled for today.

Sheriff's deputies are asking for anyone with information to call to call 911 or 88-CRIME (882-7463).
