Two Missouri residents, Joshua Young and Corinne Wallen, were found dead in an SUV parked along a mountain highway in west Jefferson County. The couple had been traveling across the country and had no known connections to Colorado. A passerby noticed the vehicle was parked for at least two days and stopped to check on it. Both men appear to have died from gunshot wounds to the head. The Jefferson County Coroner's Office is investigating the cause and manner of death.
