(WISCONSIN) -- Wisconsin policeÂ continue toÂ investigateÂ a Saturday shooting at a casino where a former restaurant employee opened fire inside the business -- killing at least two former coworkers and injuring a third.
50 people were inside the establishment, the Duck Creek Kitchen + Bar, which is near Green Bay, at the time of the shooting,Â Brown County SheriffÂ Todd DelainÂ said MondayÂ at a news conference.
The restaurant is located inside a Raddison Hotel, which is connected to the Oneida Casino, so several hundred individuals were nearby the scene of the shooting when it happened.
Delain said the suspect carried out the shooting with a 9mm handgun, where he ambushed several employees at the restaurant'sÂ waiter station.Â Â
Delain has identified the slain employees asÂ Ian Simpson, 32, andÂ Jacob Bartel, 35.Â The third employee, identified as 28-year-oldÂ Daniel Mulligan, is hospitalized in serious but stable condition.
Police has since identified the gunman asÂ 62-year-oldÂ BruceÂ Pofahl, who was shot and killed by police at the scene. Delain said the suspect was fired from the restaurant earlier this year and was bannedÂ fromÂ the complex.
The nature of the gunman's firing, as well as his motives, remain unclear.Â
