Wichita ? Wichita police say gunmen who shot and killed a 13-year-old boy at his front door had gone to the wrong house.

A police spokesman told KAKE-TV the boy was shot multiple times as he answered a knock at the door early Sunday.

Police say the gunmen were retaliating for a fight among neighbors during the Memorial Day weekend. But the man the suspects were targeting doesn’t live in the house.

Three suspects were arrested after neighbors saw them running away and called police. A fourth was arrested Sunday night.
