3 painters found dead in Rancho Cucamonga house; cause is mystery Authorities are investigating the deaths of three painters found inside a Rancho Cucamonga home Friday afternoon. A woman who hired the three men as contractors to paint the interior of her home on the 8400 block of Autumn Leaf Drive returned to check on them about 2:52 p.m., found them unconscious on the floor and called 911, fire and sheriff's officials said. The men, identified by the coroner's office as Francisco Corado, 27, of Cathedral City, Oscar Aguirre, 44, of Cathedral City and Jahiron Aaron Mejia-Morales, 24, were pronounced dead inside the single-family home. There were no signs of trauma on the men or indications of foul play, officials said. In a bathroom, fire crews found a gas-powered air compressor that had run out of fuel and had stopped operating, said Kelley Donaldson, a spokeswoman for the Rancho Cucamonga Fire District. Fire crews used carbon monoxide detectors to test the air in the home but didn't find elevated levels of the toxic gas when they arrived on scene, Donaldson said. The San Bernardino County coroner's office will conduct an autopsy on each victim next week to determine the cause of death.
