5 killed in shooting at Molson Coors campus in Milwaukee

Molson Coors CEO Gavin Hattersley spoke briefly at a press conference Wednesday night, thanking law enforcement officials and asking that locals in Milwaukee do what they can to support those who were affected by the shooting. "This is an unthinkable tragedy for us," he said.

"It really is very important that we keep them all close in the days and weeks that are coming," Hattersley said. "All across Milwaukee and Wisconsin there are folks that are associated with our employees at Molson Coors and I'd ask you to stay close with them, particularly the families of those who lost their lives today. We … are going to require a lot of support over the coming days and weeks, and I'd like to thank you all for all the support we've already received."

Milwaukee police chief Alfonso Morales said none of the victims of the shooting would be identified until at least Thursday morning. Morales cited family members coming from out of town, and a desire to respect their wishes and the grieving process.

Wisconsin Governor Tony Evers said in a statement Wednesday that "We are still learning more details about what happened at Molson Coors earlier today. What we do know, though, is that more lives were lost in a mass shooting in Wisconsin."

Evers thanked first responders who "who acted quickly to contain the situation and get folks and students in the nearby areas to safety."

"Our hearts go out to the families of those whose lives were senselessly taken, all of the folks and workers at Molson Coors, and the Milwaukee community as we grapple with yet another act of gun violence that will have long-lasting consequences for this community and our state," the governor added.

Molson Coors announced their Milwaukee office and brewery will stay closed for the rest of the week following a shooting that left five employees and the shooter dead.

"We're closing our Milwaukee office for the remainder of the week and the Milwaukee Brewery will remain shut down for the time being as well to ensure our people have time to cope with today's events," Molson Coors CEO Gavin Hattersley said in a statement. "We ask that everyone be respectful of how our colleagues in Milwaukee are feeling during this incredibly difficult time and do what you can to be supportive."

"There are no words to express the deep sadness many of us are feeling right now. I am on my way to Milwaukee now because in the hours and days ahead, the most important thing is that we support and care for each other," Hattersley added.

Milwaukee police confirmed five Molson Coors employees were killed.

The suspect, a 51-year-old man, was also found dead of an apparent self-inflicted gunshot wound, according to police Chief Alfonso Morales.

The victims have not yet been publicly identified. Morales said more information would be provided later tonight by Molson Coors executives, who are returning from a conference in Houston.

Mayor Tom Barrett also spoke at the press conference, saying "this is a tragic day for our city. This is a tragic day for our state."

"Six families are grieving and will be grieving because of this horrific act," he added.

Wisconsin Governor Tony Evers called for a brief moment of silence.

Several Democratic presidential candidates shared words of sympathy on Twitter.

"I'm devastated for the victims, and my heart is with their loved ones and all those affected by this tragedy," wrote Senator Elizabeth Warren. "We shouldn't have to live with this constant horror and grief. We need to act now to end the gun violence epidemic."

Former mayor of South Bend, Indiana, Pete Buttigieg tweeted, "We mourn another devastating tragedy. My heart goes out to all who lost loved ones. May we find the strength and will to act against gun violence, and never accept the unacceptable."

"Thinking of of the families of the victims and co-workers at Molson Coors tonight. Yet another tragic case of gun violence. Enough," Senator Amy Klobuchar said.

Schools close to the Molson Coors complex were placed on lockdown due to the shooting, but students have been since been released.

"He had called me and told me that they were all on lockdown, they can't even leave their classrooms," Ryan Hull, the father of a student at one of the schools told CBS News.

After being released, Hull's son said, "All of us were just kinda in shock because we didn't know what was happening."
