Suffolk County police are investigating the death of a man whose body was found after a fire in an abandoned Moriches house on Wednesday.

At 11:50 p.m., a 911 caller reported a fire at 151 Montauk Hwy, at a residential building on the property of a former garden structure, the Center Moriches Fire Department said. After the blaze was extinguished, the man’s body was found in the house, police said.

The man’s identity and cause of death is unknown, but will be determined after an autopsy by the Office of the Suffolk County Medical Examiner, police said.

The Center Moriches Fire Department, as well as the Mastic, Brookhaven, East Moriches and Manorville departments, responded to the scene. 

The building was destroyed but the structure is still standing, the Center Moriches Fire Department said. 

Following a preliminary investigation, detectives believe the cause of the fire to be noncriminal.
