The sheriff's office in Pinal County is investigating after they believe a butane hash oil lab started a fire and injured one man in Queen Creek.
According to officials, shortly before 10 p.m. on Friday, crews were called out to a house fire near Hunt Highway and Johnson Ranch Boulevard.
Once inside, firefighters discovered a man who had been severely burned.
He was taken to the hospital and is in extremely critical condition after suffering third-degree burns to his head, arms, and legs. The man also has severe heat and smoke damage to his lungs.
Deputies say the fire spread to a neighboring home and prompted an evacuation of two other homes. No one else was injured from the incident.
Investigators believe the cause of the fire was an active BHO lab in the home.
Authorities say more than 70 cans of butane were found inside the home, including a BHO extractor, raw marijuana, and butane honey oil.
Deputies also found remnants of marijuana grow at the home.
Detectives are working with the Pinal County Attorney on charges at this time.
