EVANSTON (WNE) — The driver who police say rear-ended another vehicle on Interstate 80, causing a crash that killed two people, has been arrested and charged with two counts of aggravated homicide by vehicle, driving while under the influence and causing serious bodily injury and reckless driving.

On Sunday, July 18, Braylin Scott Wertenberger of Boulder, Colorado, slammed his GMC Sierra pickup into the back of two cars that had stopped near milepost 1 on I-80 due to another accident a half-mile further east.

The pickup Wertenberger was driving collided with a Toyota Rav4, which was pushed into the Ford truck in front of it. Three people in the Toyota were taken by ambulance to the hospital where one, a 12-year-old Riverton boy was pronounced dead. The boy’s grandfather who was driving the Toyota and also from Riverton, later succumbed to his injuries.

According to an affidavit filed by Wyoming Highway Patrol Trooper Scott Neilson, who investigated the crash, a witness described the GMC pickup — which was three months overdue for registration — as traveling approximately 85 miles per hour as it approached the slow-moving and stopped traffic.

Neilson was advised that multiple pipes and tinfoil containing black, burnt apparent drug residue consistent with heroin use, as well as several butane torches and lighters, had been discovered throughout the GMC.
