The Iowa State Patrol has confirmed a second fatality has occurred following a weekend crash on Interstate 80 in northeast Des Moines. The driver of a 2016 Ford Focus, 22-year old Austin Paul Gainuss, of Des Moines, died Tuesday at Methodist Hospital in Des Moines, where he had been flown to by medical helicopter after his car was struck from behind by a speeding pickup truck. The accident happened at around 10:10-p.m. Saturday near the east mixmaster (the I-80/I-235/I-35 interchange). After the impact, both vehicles entered the north ditch, where the car struck a tree.

Authorities say they think 37-year-old Travis Gonzales, of Bondurant, was under the influence when his 2018 GMC pickup rear-ended the car. A passenger in the Ford, 24-year-old Joshua Lamont Cox, of Prairie City died at Mercy Hospital shortly after he was transported there by ambulance, Saturday. Both men in the car were wearing their seat belts. Gonzales was able to walk away from the crash uninjured.

The accident remains under investigation, with charges pending the results of toxicology tests.
