The Iowa State Patrol has released the names of the victims who died in Monday afternoon’s fiery crash on Highway 20 near Holstein, in northwest Iowa’s Ida County. Officials say 55-year old Michael Hengel, of Milwaukee, WI, and 38-year old Cory Severson, of Pine River, WI died in the crash that took place at around 1:25-p.m.  Two other people, 45-year old Oscar Alonzo, of Miami, FL, and 55-year old Jeffrey MacGregor, of Spencer, IA, were injured.

Officials say a 2009 Pontiac G-6 driven by Michael Hengel, was stopped in a construction zone westbound on Highway 20 behind a 2007 Freightliner semi driver by MacGregor, while the drivers waited for a Pilot car. The Pontiac was rear-ended by a 2007 Freightliner semi, driven by Oscar Alonzo. The impact shoved the car into the rear of the first semi. The vehicle then rolled on the highway and burst into flames, trapping the occupants, who perished in the fire. Alonzo’s semi entered the north ditch and rolled over following the collision. He was  transported by Holstein Ambulance to Horn Memorial Hospital in Ida Grove. Officials say MacGregor did not require transport to the hospital.  

Authorities say no alcohol or drugs were involved. The crash remains under investigation, and anyone with information concerning the accident is asked to contact the Iowa State Patrol at 712-263-4621.
