Iowa Tow Truck Drivers Struck and Killed

The cause of a crash that killed the four men on Interstate Highway 80 in Poweshiek County, about 50 miles east of Des Moines, Iowa remains unknown, authorities said Wednesday. Towing industry workers said the accident highlighted the need for drivers to pay attention and, when they see people working on the shoulder, get over, as state law requires.

Hanifen Towing drivers Jesse J. Inman, 29, of Ankeny and Daniel Walsh, 60, of Des Moines died while trying to help an Illinois man whose semitrailer had broken down. Another truck crashed into the vehicles, killing its driver and the other three men.
