RELATED: One dead in Longview duplex fire
What caused Miller's death still has not been determined, and the source of the fire hasn't been found. A fire that gutted the duplex, displacing the occupant who lived across from Miller.
"This is a duel investigation at this point between the fire department and the police department," said Longview Police Sergeant Shane McCarter.
A small army of investigators is looking into variables now. Not only how and where the fire started, but they're also looking for Miller's vehicle which has disappeared.
Investigators are looking for Miller's 2002 blue Dodge Caravan which hasn't been seen since before the fire.
"I would see him in the mornings. He would get in his car and drive off in the mornings," said one neighbor.
Fire marshals and evidence investigators have worked over 24 hours trying to find clues.
"We have a deceased individual inside that location. We will carry forward this investigation so we don't miss any of the pieces determining what the outcome of that autopsy is," McCarter says.
The release of the preliminary autopsy only added more questions.
"Hemorrhage of anterior neck muscles, near total body surface area burns, no soot in the airway. The preliminary manner of death and the cause of death are both pending," said Precinct one justice of the piece Tim Bryan.
Finding Millers van may turn up the answers they're looking for. Police say the vehicle they're looking for is a blue 2002 Dodge Caravan, Texas license plate, with the numbers B-G-6-W-7-9-8.
