Utah man accidentally killed his girlfriend after deciding to make out with her at worst possible moment

A Utah dad crashed his car and killed his girlfriend when he tried to kiss her while high on drink and drugs.

Chase Allen Bosshardt, 32, of Toquerville, was driving along Highway 10 north of Minneapolis when he delivered the fatal kiss to Ashley Cheyenne Jones on July 19.

A witness told police the Kia Soul was 'traveling so fast that it was bouncing as it went through dips in the road', before it swung left into the path of a BMW SUV travelling in the opposite lane.

Jones, 36, was declared dead at the scene while Bosshardt was treated for minor injuries at Mercy Hospital in Coon Rapids where he was charged with criminal vehicular homicide.

He is due to appear at Sherburne County District Court after he is released from hospital.

Bosshardt admitted smoking marijuana and drinking until 6am the night before

The 32-year-old said his girlfriend was not wearing a seatbelt at the time of the crash

Bosshardt told a trooper that he had been smoking marijuana and drinking until 6am the night before.

He also said he did not think Jones, from Moutain Ranch in California, was wearing a seatbelt at the time of the crash.

After waking on July 19 he had joined Jones at McCoy's Pub in Elk River where he had one tall beer, but nothing to eat before getting into his car,' he told police.

But a staff member told investigators that Bosshardt drank two tall beers, a smaller beer and a mixed drink at the bar before the couple headed off.

He was still over the legal limit of 0.8 percent blood alcohol concentration by the time he was tested in his hospital bed and admitted he had been 'making out in the vehicle before the crash occurred'.

A Minnesota State Police report noted that Bosshardt's car was making a left turn off the westbound lane when the collision took place.

Jermarquis Echols, who was driving the BMW said he hit the brakes when he saw the Kia veer across his path but could not stop in time to avoid the crash.

The 46-year-old from Afton, in Minnesota, was travelling with his partner Jennifer Reich, 45, and their 17-year-old daughter Elliana, and all were treated for minor injuries at the same hospital as Bosshardt.
