FERNLEY, NV - Lyon County detectives say two teens are dead due to possible carbon monoxide poisoning.

Shortly before midnight Tuesday night, emergency crews responded to the 200 block of Sandia Drive in Fernley for a report of two unresponsive teenagers. A boy and a girl were in a parked late-nineties Toyota 4Runner, which belonged to the boy. It was parked in front of the home of the girl, Alondra Rivera, whose identity was confirmed by her stepfather. The Lyon County Sheriff's Office confirms the boy was Zack Dwyer.

Emergency responders performed CPR, but were unable to revive them, and the 16-year-old teens were pronounced dead.

Lyon Detective Lt. J.L. Pattison tells KOLO 8 News Now a preliminary investigation indicates carbon monoxide poisoning from the running vehicle resulted in their deaths, and that there was a leak allowing the gas into the car that likely put the teens to sleep. He says no foul play or suicide are suspected.

Pattison says the two may have gone four-wheeling and damaged the tailpipe system, causing exhaust to fill the cabin.

Autopsies and toxicology tests will be performed to determine exact causes of death.
