Investigators believe the suspect had a “personal relationship” with an employee at the Duck Creek restaurant inside the Radisson Hotel & Conference Center, which is attached to the Oneida Casino near Green Bay, Wisconsin, Pawlak said.
The person the gunman was targeting wasn’t at the casino at the time, so the gunman instead shot the intended target’s “co-workers or friends,” Pawlak said.
Two witnesses described the scene as chaotic, saying they heard gunshots and saw people running for their lives.
“Pretty thankful we could get out of there, and all of us are safe,” Luehring said.
Adam Olig, also of Mayville, told the station the scene was chaotic.
“Seen people that were a lot closer. There were people running all over the place, running for their dear lives,” Olig said.
“It was chaos all over. People scattering in all directions. It was just crazy. Just crazy,” Luehring added.
Oneida Police asked the sheriff’s office to investigate the homicides and the shooting, and it asked the Wisconsin Division of Criminal Investigation to handle the police shooting of the suspect.
The names of the suspect, victims and officers involved will not be released Sunday, according to the Brown County Sheriff’s Department. Further details will be provided Monday.
“The Oneida Nation provides extremely broad security and surveillance throughout our properties and the highest level is present at our casino properties,” the nation said.
