Three Iowans were killed in three separate traffic accidents this weekend. On Friday night, Des Moines police say a man was struck by a car while riding a horse. The initial collision threw 26-year-old Dennis Kaiser of Des Moines into another lane of traffic, where he was hit by a second vehicle. Kaiser died from his injuries on Sunday.

The horse was euthanized after it was hit by yet another vehicle. Police say two of three motorists involved fled the scene. No one has been arrested in the case.
