Five workers were killed when a gunman opened fire at the Molson Coors complex in Milwaukee, police said.
The suspected shooter, a 51-year-old man from Milwaukee, died from a self-inflicted gunshot wound, police Chief Alfonso Morales told reporters.
"It's a horrible, horrible day for the employees here," Mayor Tom Barrett told reporters. "It's a very rough day for anybody who's close to this situation."
The facility in Milwaukee comprises corporate offices and two breweries, which according to the Milwaukee Journal Sentinel, have about 750 employees.
US President Donald Trump called the shooter a "wicked murderer" and offered his "deepest condolences" to the victims and families.
"Our hearts break for them and their loved ones," Trump told reporters during a coronavirus briefing at the White House.
For several hours, dozens of police officers, SWAT teams and FBI agents were seen walking in and near the sprawling complex of breweries and corporate offices.
Police have released few details but say there's no active threat at the complex.
Molson Coors said it was working closely with police. "Our top priority is our employees and we'll provide updates in conjunction with the police as we are able," the company tweeted.

US Senator Tammy Baldwin of Wisconsin described the incident as a mass shooting.
"Gun violence has taken too many lives in Milwaukee and the mass shooting today is heartbreaking," Baldwin tweeted.
"I want to thank the first responders who ran into harm's way and saved lives. My office is standing by to help the #MKE community in the wake of this tragedy."
The facility is also home to corporate customer service, finance, human resources and engineering.
Tours take people to underground caves where beer was once stored, a saloon with intricate woodwork, a stein hall with stained-glass windows, a champagne room meeting hall with leaded-glass windows, and an outdoor beer garden that can hold 300 people.
Earlier James Boyles told the Milwaukee Journal Sentinel that his wife, Lasonya Ragdales, works at Molson Coors in the claims department.
She was texting from inside the building and told her husband that there was active shooter and she was locked in a room with a bunch of co-workers, the Journal Sentinel reported.
