JERSEY CITY, N.J. (CBSNewYork/AP) — Prosecutors say a retired police officer found strangled in his Jersey City home this week apparently died during a botched burglary that turned violent.

Authorities say 68-year-old Frank Goggan, who was on the force more than 30 years, was discovered face-down on the living room floor at his home on Seaview Avenue on Thursday.

His body was found after a concerned resident said he hadn’t seen the normally active man since Monday and called police.

A preliminary autopsy report states Goggan suffered trauma to his head and neck and broken ribs. Hudson County Prosecutor Edward DeFazio said the victim died from blunt force trauma and asphyxiation due to strangulation.
