State fire investigators say they believe the man whose body was discovered following an explosion and a fire at a Palermo home late Monday was Gary Crane Sr., 64.

Crane’s son, Gary Crane Jr., 45, remains in critical condition at MaineHealth Maine Medical Center in Portland.

In an update, Shannon Moss, public information officer for the Maine Department of Public Safety, said the incident remains under investigation.

Shortly before 11:30 p.m. Monday, the Palermo Fire Department responded to a report of a structure fire at 98 Leeman Arm Road, and found the home engulfed in fire.

They also found a severely burned man, the younger Crane, in the road near the home. He had apparently escaped the fire. Before he was taken by ambulance to MaineGeneral Medical Center, he said a person was inside the home. He was later taken via LifeFlight of Maine to the Portland hospital.

Several area fire departments and ambulances responded, and six investigators from of the Office of State Fire Marshal were deployed.

On Tuesday, fire investigators recovered a body, which was taken to the Office of Chief Medical Examiner in Augusta.

Lindsey Chasteen, director of operations for the Office of Chief Medical Examiner, said the office is working to scientifically identify the victim, and it’s too soon to know the cause and manner of death.

At that point, investigators said they believed an explosion occurred before the fire. The home used propane gas for both appliances and heating.
