US police have identified the gunman in the Milwaukee brewery shooting as an electrician whose home was searched earlier in the day.
Milwaukee police chief Alfonso Morales said the gunman was 51-year-old Anthony Ferrill.
Morales identified the victims as Molson Coors Brewing Company employees ranging in age from 33 to 57.
He said police are still investigating a motive.
Police searched Ferrill's home on Milwaukee's north side as they hunted for clues about why an employee at one of the nation's largest breweries gunned down five co-workers before taking his own life.
The house, a one-storey home with a massive jungle-gym in the backyard, was roped off with crime scene tape on Thursday morning.
A police car sat in the driveway and a police van was parked at the curb.
Investigators could be seen entering the house.
Neighbour Erna Roenspies, 82, said Ferrill has worked at the brewery for 15 years as an electrician.
The shooting happened on Wednesday afternoon at Molson Coors' massive brewery complex in Milwaukee, which employs about 1000 people.
The brewery complex includes a mix of corporate offices and brewing facilities
It is widely known in the Milwaukee area as "Miller Valley", a reference to the Miller Brewing Company that is now part of Molson Coors.
A massive red Miller sign that towers over the complex is a well-known symbol in a city where beer and brewing are intertwined with local history.
The complex features a 160-year-old brewery, a packaging centre that fills thousands of cans and bottles every minute and a distribution centre the size of five football fields.
