WALL, S.D. (AP) — A one-vehicle crash on Interstate 90 near Wall over the weekend killed one man and injured four others from St. Louis.

The South Dakota Highway Patrol on Monday identified the fatal victim as 21-year-old Andrii Ponomar. He was one of five occupants in the vehicle that went in the ditch and rolled shortly after 10:30 a.m. Sunday.

Authorities say the incident happened when 20-year-old Mykola Serhiienko lost control of the 2004 Pontiac Vibe he was driving. They say Serhiienko, 20-year-old Artem Boiko and 20-year-old Artem Kurhan suffered injuries that are serious but not life-threatening.

Another passenger, 29-year-old Ivan Iskorostenskyi, suffered life-threatening injuries.

The Highway Patrol says Ponomar was pronounced dead at the scene. The agency says only the driver was wearing a seatbelt.

The incident remains under investigation.
