Three people were killed Saturday night, including a suspect, after a shooter opened fire at a hotel connected to a tribal casino near Green Bay, Wisconsin, authorities said.
The gunman was targeting a worker he knew at the Duck Creek Kitchen + Bar inside the Radisson Hotel & Conference Center in Ashwaubenon, Wisconsin, but the person wasn't there, said Lt. Kevin Pawlak of the Brown County Sheriff's Office.
Instead, the suspect opened fire on two of the target's coworkers, killing them, Pawlak said, and officers fatally shot the suspect outside the hotel connected to the Oneida Casino.
A third person was "seriously injured" by gunfire and being treated at a Milwaukee hospital, Pawlak said.
Melinda J. Danforth, director of intergovernmental affairs for the Oneida Nation which operates the casino, said as many as seven or eight people may have been hit, but she was unsure of the exact number.
Police cleared rooms in the hotel, just to be safe, after the gunfire broke out, Danforth said, adding: "Crowd control is an issue for us because people are trying to see what’s happening."

The casino tweeted earlier that it was contending with "an active shooter situation" and that several law enforcement agencies were at the scene.
Jawad Yatim, a witness, told the Associated Press that the gunman "was shooting pretty aggressively in the building, so I wouldn't doubt him hitting other people."
Yatim said the shooting began in a casino restaurant."We got the hell out of there, thank God we're OK, but obviously we wish the best for everybody who's been shot," he said.
Attorney General Josh Kaul tweeted shortly before 10 p.m. that the scene was "contained."
Wisconsin Gov. Tony Evers said on Facebook that he and his wife, Kathy, "were devastated to hear about the shooting at the Oneida Casino complex tonight. Our hearts, thoughts, and support go out to the Oneida Nation, the Ashwaubenon and Green Bay communities, and all those affected by this tragedy."
