Friday marks one year since a gunman opened fire and killed five co-workers at the Miller brewery in Milwaukee.The victims were Dale Hudson, Gennady Levshetz, Jesus Valle Jr., Trevor Wetselaar and Dana Walk.It's a loss their families are still feeling today.Janet Wetselaar lost her son Trevor, a powerhouse operator at Molson Coors and Navy veteran who worked on a nuclear submarine."Our entire family has been devastated, and every day and night is filled with extreme misery and sadness," she told WISN 12."It has been a very difficult year for the family without Dale and our hearts are slowly healing," Hudson's widow, Kathleen Hudson, said.For these families, time has not yet healed their deep wounds. The beermaker and its staff are still healing, too."Our employees have been incredibly resilient. I think they've taken comfort speaking with one another, speaking with counselors. They've shown an incredible amount of grit and determination to recover from this," Molson Coors community affairs director Tami Garison said.Molson Coors offered Friday off to all brewery workers and will have a moment of silence companywide. It also dedicated a memorial to the victims last fall."As a company, we're trying to make sure we're doing everything to support those range of emotions," Garrison said.The shooter, Anthony Ferrill, took the lives of his co-workers then turned the gun on himself."Are we any closer today to figuring out a motive for this deadly violence?" WISN 12's Hillary Mintz asked Garrison. "That's a fair question, but I'm not the Milwaukee Police Department, and I can't answer that question for you," Garrison said.A year later, no answers and no closure for the families -- something they say they may never have.Molson Coors set up a fund for the victims' families which raised more than $1.8 million.
