Earl J. Kerr, 75, of Alexandria Township was found dead in his home Friday.
His son Roy Kerr, 55, is in custody and charged with aggravated assault.
When troopers from New Jersey State Police Barracks in Kingwood conducted a welfare check at the Kerr residence Friday, they discovered the 75-year-old was deceased.
That evening, detectives from the state police and Hunterdon County prosecutor’s office arrested Roy Kerr.
He is in the Hunterdon County Jail, charged with second degree aggravated assault. The Honorable H. Matthew Curry set bail at $100,000.
Earl Kerr’s body was taken to the Hunterdon County Medical Examiner’s Office where an autopsy was performed. As of Monday afternoon, that office had not concluded its investigation and results are pending on cause and manner of death.
"This remains an open and active investigation,” said Hunterdon County Prosecutor Anthony P. Kearns III in a news release.
“Our condolences go out to the Kerr family. We commend the troopers and detectives involved in this investigation."
Kearns said the New Jersey State Police Major Crimes Unit, Crime Scene Investigation Unit and Kingwood Station Detectives along with his Major Crimes Unit conducted the investigation of the crime scene.
