Transcript for 6 dead, including gunman, after mass shooting at Milwaukee brewery
You bet. We turn to another big story, that shooting at a moulson coors facility in one much the worst mass shootings in the state's history. Police say an employee went on a rampage killing five co-workers before taking his own life. Alex Perez is there. Good morning. Reporter: For more than a thousand people, it started out pretty normally until about 2:00 in the afternoon when suddenly everyone's worst nightmare became a reality. This morning, tragedy at a Milwaukee landmark. Never seen anything like this. Reporter: Police say an employee opened fire at the old Miller brewing headquarters, now the moulson coors company killing five co-workers before turning the gun on himself. A shooter is still at large. We've got one man down. Reporter: Investigators say the former employee returned to the office armed opening fire on staff members. Employees were evacuated along with neighboring schools as police searched more than 20 buildings on the campus. I was able to get here on time and get him home. We didn't know what was going on. Reporter: This worker says he walked away from the gunman to talk to someone else just seconds before the shooter pulled out the gun. If I wouldn't have gone to talk to this guy, I'd be one of them guys. I know that for a fact because I would have walked right into what was going on. Reporter: More than a thousand people were working at the sprawling plant Wednesday afternoon when the shooting occurred. This Miller brewing site has been part of the Miller family and part of the city of Milwaukee for 165 years, and this is the saddest day that we have had. Reporter: And authorities at this point have not released any other details on the 51-year-old gunman or his employment history. This community now coming together to mourn those that were killed. Robin. We're certainly thinking of everyone there. Alex, thank you.
