Fire crews were called to the 5500 block of Newtown Avenue , near Tacony Creek Park for a rubbish fire.
According to police, crews instead found a man bound and set on fire.
The victim's arms, ankles and neck were tied up with an electrical cord.
His body was also tied to a garage type floor jack used to change tires.
Police say the jack may have weighed 50 pounds.
There was also evidence of rags stuck in containers and a strong gas odor.
The victim was found on the side of a desolate road in an unlit wooded area.
An autopsy will be done to determine the identity and if the victim died before or after he was set on fire.
