GUERNSEY, Wyo. – Oct. 28, 2025 – Following extensive investigative efforts, the Wyoming Department of State Parks and Cultural Resources, Division of State Parks’ Law Enforcement Rangers, in cooperation with the Platte County Sheriff’s Department, are seeking the public’s help identifying a male suspect connected to a felony assault that occurred at Guernsey State Park on the evening of Aug. 9, 2025.
Despite continued investigation and collaboration between agencies, efforts to identify the suspect have been inconclusive, prompting this public appeal for information.
The suspect is believed to have caused serious bodily injury to the victim during the incident. He was last seen as a passenger in a late-1990s Nissan pickup truck with an oversized slide-in camper, driven by another male. The vehicle is believed to have Wyoming registration beginning with “2T,” originating out of Laramie County.
“We’ve followed every lead to no avail and are now asking for the public’s assistance,” said Ranger Captain Corey Jacobsen. “Even a small piece of information could make a big difference in helping us identify this individual and bring closure to the victim.”
The investigation remains active, and our agencies continue to pursue all available leads.
