The bodies of the partially clad couple, both 40 years old, were found inside the vehicle, which had run out of gas but had the ignition switch still on, reports the Patriot-News. A kerosene heater was also on and there were very high levels of carbon monoxide in the garage. Marijuana and drug paraphernalia were also found in the car and it appears Keith Payton and Salina Johnson may have been using drugs at the time, the coroner tells WNEP. They were pronounced dead Friday night, but likely died earlier; police say Payton was supposed to drop something off at the garage for his brother on Thursday. They weren't the only couple to die at the hands of carbon monoxide in recent days. The AP reports that a Utah couple died while cleaning carpets on Saturday. Maria Lopez-Landaverde, 37, and Joselito Solorzano, 43, ran a carpet cleaning business, and left their van running in a shut garage while tending to a West Jordan home. Police cited a lack of ventilation in the home.
