A video shows officers failed to guard an Iowa drunken driving suspect who escaped from a State Patrol car while handcuffed and was struck by a van and killed.

Matthew Lentzkow's death has brought attention to how Iowa State Patrol vehicles lack cages to transport suspects to jail.

Lentzkow's father, Gary Lentzkow, says the trooper who made the Nov. 1 stop and two sheriff's deputies who arrived as backup should not have allowed his son to unbuckle himself and get out of the patrol car.

Jasper County Sheriff John Halferty says officers in hindsight should have put the 36-year-old Newton man in the cage of a sheriff deputy's car and had someone watch him.

He says the officers believed they were doing everything right at the time.
