Authorities in Massachusetts have charged a 42-year-old man with the murder of a Maine chef found dead, wrapped in blankets and sealed with duct tape, in the back seat of his car last month at a Weymouth hospital.

The district attorney’s office of the Plymouth District said that Christopher Caron surrendered to Scituate Police on Saturday as investigators were preparing to track him down. He is expected to face a murder charge in court on Tuesday in the death of 27-year-old Declan Perry.

The investigation began on August 23 when a man later identified as Caron drove Perry’s black Honda Civic to the emergency room of South Shore Hospital, “alerted medical staff of a body within the vehicle,” then fled the scene. Medical personnel found the body “wrapped in multiple blankets secured with duct tape.

A major break in the case came when a resident of the Driftway condo complex in Scituate contacted police after seeing news reports about the body found outside the Weymouth hospital. They told detectives that they had assisted Caron “loading a large, heavy blanket into the black Honda Civic” outside the condo where Caron lived.

Court documents say Caron told the neighbor the object in the blanket was “a hockey goalie mannequin which was usually filed with water,” WFXT reported.

The station said that police seized a belt, a pair of scissors, a wooden door, a pair of sandals, two web cameras, a piece of mail, a medical document, and swabs of a reddish-brown stains while executing a search warrant in a condo.

The medical examiner has not yet revealed Perry’s cause of death.

WMTW reported that Perry was a beloved chef at The Grill Room in Portland.
