DES MOINES, Iowa -- The Des Moines police and fire departments responded to a serious crash around 12:15 p.m. Sunday. It happened in the parking lot of 2650 Ingersoll Avenue.
Police say the car was driving westbound on Grand Avenue just south of the lot when it left the roadway and went over a concrete walling slamming into the parking lot below.
Police identified 32-year-old Des Moines resident Grant Stokka as the driver killed in the crash. His 8-year-old son was transported to the hospital and treated for minor injuries.
A pastor says Stokka was driving home from church when the crash happened. The pastor says another family from the church witnessed the crash and said Stokka may have swerved to avoid another vehicle that he likely didn't see behind a huge pile of snow in the area.
Investigators say there is no indication that criminal action took place.
Police say witness statements and examination of the evidence indicate that impairment, excessive speed and road conditions are not contributing factors to the crash.
Investigators request that any potential witnesses who were in the area of the crash contact the traffic unit at 515-323-8370
