Authorities say a man from New Jersey killed his mother inside her apartment, put her in a chest and then drove her body to a pizza shop where he worked.

According to Burlington County prosecutors, Brian Templeton, 53, has been charged with murder and desecration of human remains. Templeton is being treated at a medical facility for an “ongoing condition.”

A worker at the Courtyard Apartments complex in Edgewater Park contacted police Monday and asked them to check on Doris Templeton, 77, a resident there who had not been seen nor heard from in more than two weeks. Her body was found Tuesday afternoon by investigators at the shop in Willingboro.

An autopsy determined she died from blunt force trauma to the head.

It’s not known if Brian Templeton has retained an attorney.
