Investigators believe the suspect had a “personal relationship” with an employee of 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 shooter was targeting was not at the casino at the time, so the shooter instead shot at the intended target’s “colleagues or friends”, Pawlak said.
Two witnesses described the scene as chaotic, saying they heard gunshots and saw people running for their lives.
“I’m pretty thankful that I was able to get out of there, and we’re all safe,” Luehring said.
Adam Olig, also from Mayville, told the station the scene was chaotic.
“I saw people a lot closer. There were people running around, running for their lives,” Olig said.
“It was chaos everywhere. People were scattering in all directions. It was just crazy. Just crazy,” Luehring added.
Police in Oneida asked the sheriff’s office to investigate the homicides and shootings, and they asked the Wisconsin Criminal Investigations Division to deal with the police shooting of the suspect.
The names of the suspect, victims and officers involved will not be released on Sunday, according to the Brown County Sheriff’s Department. Further details will be provided on Monday.
“The Oneida Nation provides extremely broad security and surveillance across all of our properties and the highest standard is present at our casino properties,” the nation said.
