Authorities apprehended a man Wednesday suspected in the early morning killings of two Des Moines area police officers who were shot to death while sitting in their patrol cars in what authorities described as separate ambush-style attacks.
Officers from the Dallas County Sheriff's Office and Iowa State Patrol took 46-year-old Scott Michael Greene into custody and were taking him to Des Moines, police said.
His arrest came about eight hours after the killings to two officers.
Des Moines Sgt. Paul Parizek told CNN that he had few details about the circumstances of Greene's capture, but that Greene was on foot on a roadway at the time and was alone when he was taken into custody.
