The State Fire Marshal's Office has determined that a fire on George Washington Highway in Aurora around 4 a.m., Tuesday was intentionally set.
Accelerant samples were taken and sent to the West Virginia State Police Lab for Hydrocarbon analysis, according to a news release from Assistant State Fire Marshal Mackey Ayersman.
The resident, Charles Wayne "Randy" Teeter, sustained serious burns and is in the West Penn Burn Center in critical condition.
The kitchen stove's gas line was disconnected, which is believed to be the source of the explosion, said Ayersman.
Ayersman said a suspicious fire happened at the same location in June 2012, but it wasn't investigated by the State Fire Marshal's Office.
An Aurora man is at the West Penn Burn Center after being burned in an explosion at his home in Preston County.
Charles Teeter was badly burned after residents said they heard an explosion around 4 a.m. Tuesday, according to Clark Nicklow with Preston County 911.
Aurora Fire Department Chief Mike Gallagher said some type of gas exploded, although it's undetermined whether it was propane gas or gasoline. Gallagher said the gas oven in the trailer had been disconnected prior to the fire.
People from three miles away said they heard the explosion, Nicklow said.
Teeter was in the home at the time of the fire. The trailer is a total loss, Gallagher said.
Teeter is believed to have tried to commit arson to his home during the summer, Gallagher said.
The State Fire Marshal's Office is investigating.
