One man is dead and another was seriously injured in an all-terrain vehicle (ATV) accident southeast of North Platte.

At around 11:15 p.m., on May 31, deputies with the Lincoln County Sheriff’s Office responded to the report of an ATV accident on South Miriam Road and East Meadow Lawns Road.

It was reported that two males were injured.

Deputies and the North Platte Fire Department arrived on the scene and found that the driver of the ATV, 49-year-old Martin C. Porter, of North Platte, was deceased.  The passenger, a 48-year-old male, sustained serious injuries and was taken to Great Plains Health by ambulance.

Investigators determined that Porter was driving the ATV northbound on Miriam Road and attempted to turn east on Meadow Lawns Road.  They say Porter was unable to negotiate the corner, causing the vehicle to roll.

According to Chief Deputy Roland Kramer, seatbelts were not in use and investigators believe alcohol may have been a factor in the crash.

The investigation is ongoing, according to Kramer.
