A Bar Nunn man who admitted to being involved in a fatal two-vehicle collision west of Casper has been given his punishment..

Thirty-four year old Tracy Matekovic was sentenced to five-to-five-and-one-half years in prison, after he pleaded guilty to one charge of DUI resulting in serious bodily injury.

According to law enforcement, in December 2013, officials were called to the intersection of Highway 20/26 and North Six Mile Road west of Casper, for a two-vehicle head on collision.

Investigators say Matekovic was driving in the wrong lane of travel, when he collided head-on with another vehicle driven by 38-year old Chris Sanders, who was pronounced dead at the scene.

A Wyoming Highway Patrol trooper said that Matekovic had a strong odor of alcohol coming from him.

While at the hospital being treated, police and hospital personnel say he was causing a disturbance and was being combative at times.

He had three prior DUI’s on his record at the time of his arrest.

Matekovic's defense attorney mentioned at his sentencing, that Sanders was speeding at the time of the collision, and had meth in his system, although that is no excuse for what Matekovic did.

As a result of those circumstances at the time, the prosecution was unsure if they could go forward with a vehicular homicide charge, because Matekovic was not the sole contributor to the situation.
