Man killed in wreck exceeded intoxication limits

May 2, 2017 From staff reports

Matthew M. Morin died April 14 in a one-vehicle rollover west of Riverton.

Toxicology results show a 29-year-old Riverton man who died in a one-vehicle crash this month was intoxicated at the time.

Matthew M. Morin died at about 9 p.m. April 14 of brain stem herniation and a cerebral hemorrhage due to blunt-force injury from the crash.

His blood-alcohol content was .133. The legal limit in Wyoming is .08

Morin also had 2.3 nanograms per milliliter of Delta-9 THC in his system, plus 15 ng/ml of Delta-9 Carboxy THC.

Delta-9 THC is the short-term, most active metabolite of the drug cannabis. It shows up 6-9 minutes after cannabis is ingested and only lasts about 2 hours. The NIH and HTSA consider a driver to be impaired if they have consumed more than 5 ng/ml of Delta-9 THC.

Delta-9 Carboxy THC stays in the system longer.

The Fremont County Coroner's Office has determined Morin's death was an accident. It took place at about 7 p.m. April 14 on U.S. Highway 26 about eight miles west of Riverton. Morin was the driver and sole occupant of the white 2000 Dodge Dakota involved.

He had been traveling east toward Riverton when he reportedly made "an aggressive move to the left." Then, as the vehicle was traveling toward the ditch to the north side of the road, he steered hard to the right, officials said.

The vehicle slid driver-side first, leaving the roadway to the north and rolling multiple times. Morin, who was not wearing a seatbelt, was ejected.

He was transported from the scene by ambulance and died that night.

Fremont County Coroner Mark Stratmoen said that due to the circumstances leading up to the death, and the obvious cause of death as trauma, there was no need for an autopsy.
