An Arizona man was found dead in a rugged mountain area outside Tucson, next to a smoldering vehicle, two hours after he left home with someone who asked for help with car trouble.

The Pima County Sheriff’s Department has been circumspect with information since finding Paul Clifford’s body at about 1 a.m. on December 24, miles from his home, KOLD reports.

The sheriff’s department said it responded to the remote area east of Tuscon on a call of suspicious activity. There, on a remote dirt road, they found the burning vehicle and Clifford’s body nearby. Detectives said they found information that led them to believe the activity there was related to a stolen vehicle.

Clifford’s daughter, Sabrina Vining, posted on Facebook that her 53-year-old father had taken her truck to help a stranger who approached him at his home at about 11:30 p.m. on Monday asking for help jumpstarting his vehicle. When he didn’t return home, the family tracked the truck and gave that information to police, who found it at an apartment complex in Tucson.

No arrests have been made.

“I don’t think that there’s anything that says this is ongoing,” Deputy Adam Schoonover said, “but with this type of incident you never really know and so it’s always good to be on-guard. If something doesn’t feel right, don’t go through with it. Maybe, just tell the person you can’t help them out or maybe take somebody with you or whatever the case may be.”

Police have not said how Clifford was killed.
