Two Sioux City residents died and another was injured during a crash on Interstate 80 Sunday morning about a mile east of Casey, in Adair County. The Iowa State Patrol says 58-year old Cynthia Piester, and her daughter, 38-year old Jennifer Piester, died in the crash. Cynthia’s husband, 60-year old Johnny Piester, who was driving the SUV, was injured, and transported by Stuart Rescue to Mercy Hospital in Des Moines, where he was listed in fair condition Sunday night.
Officials say Piester’s 2000 Chevy Trail Blazer was traveling east on I-80 at around 10:50-a.m., when, for reasons unknown, the SUV entered the median, went between the bridges of the Middle River, and came into contact with the rock embankment. The vehicle rolled onto its roof, made contact with the west bank of the river, and slid across the river ice before coming to rest partially submerged on the east bank of the river.
All three of the accident victims were wearing their seatbelts. The accident resulted in the east and westbound inside lanes of I-80 being closed. The westbound inside lane was closed for about two hours, while the eastbound inside lane remained closed for a little more than four-hours.
The accident remains under investigation.
