Two people were shot to death and another was wounded during a third night of protests in Kenosha over the police shooting of a Black man, Jacob Blake, and authorities on Wednesday hunted for a possible vigilante seen on cell phone video opening fire in the middle of the street with a rifle.

The gunfire was reported just before midnight, and Sheriff David Beth said one victim was shot in the head and another in the chest, the Milwaukee Journal Sentinel reported. The third victim's wounds were not believed to life-threatening. He said investigators had reviewed footage of what happened and that he was confident a man would be arrested soon.
