Authorities in Wisconsin say a gunman killed two people at a Green Bay casino Saturday night and seriously wounded a third before he was shot and killed by police. Brown County Sheriff's Lt Kevin Pawlak said investigators believe the gunman was targeting a specific person he was angry at, but the person wasn't at the Oneida Casino at the time.

The gunman 'decided to still shoot some of the victim's co-workers or friends, it appears,' Pawlak said. The attack happened around 7:30 p.m. at the Oneida Casino, operated by the Oneida Nation on the western side of Green Bay. Attorney General Josh Kaul tweeted shortly before 10 pm that the scene 'is contained. There is no longer a threat to the community.'
