One man was killed and three others injured Friday night when a car went the wrong way on Interstate 29 south of Crescent, Iowa.
The dead man was identified Saturday as David D. Miller, 33, of Benton, Ark.
Miller was driving a KIA Spectra north in the southbound lanes, the Iowa State Patrol said.
The KIA collided head-on with a Nissan Maxima driven by Fredy Zanabria, no age or hometown given.
Zanabria was trapped in the vehicle for about 45 minutes. He was taken to the Nebraska Medical Center in Omaha with life-threatening injuries, the State Patrol said.
Miller's KIA wound up on the road median. The Nissan careened into the west ditch, facing north.
The crash was reported at 10:35 p.m. The report of a vehicle going the wrong way on I-29 came in at 10:32 p.m.
Also injured in the crash were Cesar Caballero and Luz Trujillo, both 23 and both back-seat passengers in the Nissan. They were taken by helicopter to the Nebraska Medical Center, the State Patrol said.
Of the four crash victims, only Zanabria was wearing a seat belt.
