The victim was identified Wednesday as an 88-year-old man from Montgomery County.
Just before 5:00 PM, prosecutors announced the victim's son and grandson have been charged in connection with his death.
Detectives and investigators believe the 88-year-old victim was killed in Montgomery County and then his body was brought to Susquehanna County and dumped in a rural, wooded area of Gibson Township.
David St. Onge, Sr. is now facing third degree homicide charges.
Police in Montgomery County believe he hit his 88-year-old father in the head, killing him and then allegedly conspired with his son, David St. Onge, Jr. to get rid of the body.
The victim was found Friday morning by workers clearing brush near Route 92 in Gibson Township, Susquehanna County.
The victim, identified as Jack St. Onge, was wrapped in a tarp.
Susquehanna County District Attorney Jason Legg says there was no identification on the body but the coroner was able to identify the man because of a pacemaker.
"They were able to verify the identity of the man who died based upon a medical device in his body so they were able to track it back to him," Susquehanna County District Attorney Jason Legg said. "From there, they were able to use his driver's license info to track back the fact that he was from Montgomery County."
Police spent all day searching the 88-year-old victim's home in Montgomery County.
Investigators believe the homicide happened there. Exactly why his remains were dumped in Susquehanna County has not been released.
The area where the body was found is remote and rural and neighbors say it is a known dumping ground. Luggage, bottles and tires could be seen in the area on Wednesday.
Now that arrests have been made in the case, the Susquehanna County District Attorney expects the suspects to face charges in Montgomery County because that is where the homicide took place.
"All indications point to the fact that nothing occurred in Susquehanna County except for someone left the body of this individual in Susquehanna County," Legg said.
David St.Onge, Sr, who police believe actually killed his father, is also accused of stealing items from him and selling them.
Prosecutors say additional charges may be filed after a coroner determines exactly how the 88-year-old man died.
