(Casper, Wyo.) – Three people were killed in two separate crashes on Monday. At about 6 p.m. a Casper couple was killed in a two vehicle crash on I-25 about three miles north of Casper.

The Wyoming Highway Patrol reports that Duane Hartman, 83, and Linda Hartman, 68, both died at the scene of the crash on south bound I-25.

Investigating trooper Marshall Wyatt states Duane Hartman, the driver of a 2003 Mitsubishi Outlander, was entering onto south bound I-25 at mile post 191 and for unknown reasons turned left across both lanes of travel on the interstate.

A south bound commercial truck driven by David Dobbin, 59, of Box Elder, SD collided with the driver’s side of the Hartman vehicle in the left hand lane.

Troopers report the interstate was closed about 4.5 hours while they investigated the incident. All occupants of both vehicles were wearing seatbelts at the time of the crash.

Additionally, 59-year-old Gary Griffin of Hamburg, New York, was fatally injured June 30th at around 11:00 am when the bicycle he was riding was struck by a pickup on Wyoming 220 about 25 miles south of Casper.

Investigating Trooper Clint Haver stated Griffin was riding with a group of bicyclists when for unknown reason he turned left across the highway in front of a vehicle driven by 57 year old Melinda Sebion of Bar Nunn, WY. Sebion was unable to avoid colliding with Griffin who was transported via helicopter to the Wyoming Medical Center where he later died.

No charges are being filed in the incident. This is the third cycling fatality in Wyoming since May.
