LAS VEGAS (KLAS) — Las Vegas Fire and Rescue and Las Vegas Metropolitan Police homicide detectives were all called to the scene of a manufactured home fire on the northeast side of the valley. The fire happened at 1322 Mojave Avenue, near Charleston Boulevard.

According to Metro, when fire fighters arrived they saw the home on fire, two people fighting in front of the home, and a woman with “100% of her body” burnt. This woman was taken to UMC Trauma in extremely critical condition.

During a news briefing, Metro Lieutenant Raymond Spencer said before the fire six adults were in the home, four of them in the master bedroom, and three of those four people were in an argument over infidelity. Lt. Spencer said one of those three people lit the bed on fire but it is not clear where the woman who was critically burned was located when the fire began.

Medical responders took two other people to the hospital for smoke inhalation, and detained the other three people in the home for questioning. By 10:20 p.m. police confirmed the arrest of one woman in connection to the fire and are no longer questioning the other two.

Lt. Spencer said at this point, whoever lit the bed on fire could face an attempted murder charge and if the critically injured woman were to die that charge would change to open murder.
