(Casper, Wyo.) – Two teens, in a vehicle with several Riverton residents, were killed in a two vehicle crash on Highway 20/26 about 50 miles west of Casper on Saturday afternoon, the Wyoming Highway Patrol announced today.

Moeniqa D. Produit, 18, of Kemmerer, and Michelle M. Allen, 13, of Riverton, were both pronounced dead at the scene when the car they were in reportedly crossed the center line and struck an on-coming vehicle carrying a Fort Washakie family.

Produit was driving a 2002 Buick Lesabre and Michelle Allen was seated in the left rear passenger seat. Produit’s other passengers were Stacy Wilcox, 38, of Riverton, and Holly Allen, 9, of Riverton. Wilcox and Holly Allen were hospitalized at Wyoming Medical Center in Casper. Their current conditions have not been released at this time.

Driving the second vehicle, a 2003 Toyota Tundra, was Thomas Presgrove, 48, of Fort Washakie. His passengers were Suzanne Presgrove, 52, of Fort Washakie, and Fernalia Savage, 9, of Riverton. Both Presgroves were treated and released from Wyoming Medical Center. A private vehicle reportedly transported Savage to Riverton Memorial Hospital.

Everyone involved was wearing seat belts.

“Light snowfall was falling at the time of the crash and the roadway was partly ice covered,” states a WHP news release.

“According to witnesses, there was a pickup truck pulling a horse trailer that was jackknifed causing some lane blockage of the roadway,” the release continues. “Produit was westbound and started to slow due to the road blockage of the pickup and horse trailer ahead of her. Produit lost control of her vehicle and it crossed the center line going into the opposite lane of travel. Presgrove, who was eastbound, saw the Produit vehicle cross over into his lane and he attempted to slow down and steer towards the westbound lane of travel. His vehicle struck the Produit vehicle on the passenger side.”

The jackknifed picked and horse trailer reportedly left the scene after the driver regained control of the combination.
