Three people were hospitalized Saturday night after the vehicle they were traveling in veered off a stretch of Denison highway and crashed.

Denison Police Lt. Mike Eppler said the crash happened along a section of U.S. Highway 75, near exit 70, at approximately 9 p.m.

“The vehicle drove off the roadway there into a grassy area for darn near half a mile,” Eppler said. “It then wound up going through a fence and into a pasture, where it struck some kind a big tree stump or something and just really, really tore the vehicle up. Now, why the driver did that, we still don’t know.”

One of the occupants, a male, was flown by air ambulance to Medical City Plano with injuries that Eppler described as life threatening. The two remaining occupants were taken to Texoma Medical Center with minor injuries. Eppler said he did not have access to the victims’ names and ages Monday morning as the official crash report had not yet been submitted

The Grayson County Sheriff’s Office, Texas Department of Public Safety and Texas Parks and Wildlife officials all responded to the scene of the crash. Eppler said investigators found no sign of drug or alcohol use among the victims.
