A teen whose face was left severely disfigured from a house fire was busted for gunning down an older man and dumping his body in a Nevada desert, according to police and a new report.

Michael Miller, 19, who has also used a wheelchair since the 2003 fire, was arrested Tuesday in connection with the death of Raul Salazar, 47, authorities said.

Salazar, who had been reported missing, was discovered wrapped in a sleeping bag in a desert area off State Road 47, known as Lake Mead Boulevard, near Pablo Road, on Friday, the Las Vegas Review Journal reported.

He died of multiple gunshot wounds, and the Clark County coroner’s office said Tuesday that his death was determined to be a homicide, according to the report.

Evidence indicated that Salazar was murdered elsewhere and his body was taken to the remote area, Las Vegas police said in a statement.

Homicide detectives identified Miller as the suspect and took him into custody four days later, police said.

He was taken to the Clark County Detention Center, where he faces one count of open murder, cops said.

Miller’s uncle, Robert Miller, told the Review-Journal that his nephew was severely burned and disabled in a fire when he was only 3 years old.

His 4-year-old cousin, a girl, was killed in the blaze.

The local fire department said at the time that kids playing with a cigarette lighter sparked the accidental fire, according to the Review-Journal.

Michael Miller was homeless for part of his childhood, his uncle added.

He’d never heard his nephew speak about Salazar, nor did the man fit the description of any of the teen’s friends, he said.

The teen’s next court date is set for Friday.
