Authorities in northern Arizona say they're investigating the murder of a 17-year-old Ash Fork boy.
Coconino County Sheriff's officials didn't immediately release the victim's name Monday and they say a suspect hasn't been identified yet.
The Sheriff's Office received a call Friday about a body found near Interstate 40 just east of Ash Fork.
A gas company employee had pulled off the highway on a side road and discovered the body on the ground in a turnaround area.
Investigators say the teenage victim suffered trauma to his head.
An autopsy was conducted Monday and authorities say the cause and manner of death are pending.
Sheriff's detectives still are searching the area where the body was found for possible clues.
