The five men who were gunned down by a co-worker in a mass shooting at Milwaukee's Molson Coors brewery have now been identified.

Authorities named the victims of Wednesday's tragedy as Jesus Valle Jr., 33; Gennady Levshetz, 61; Trevor Wetselaar, 33; Dana Walk, 57; and Dale Hudson, 60.

The gunman, 51-year-old Anthony Ferrill, was also identified Thursday. He was an electrician at Molson Coors and sources allege he was involved in a dispute with one of his victims in the days before his rampage.

Police say the case is still under investigation, and they have yet to release details about how the shooting unfolded.

However, heartbreaking stories about the five victims have begun to emerge in online death notices and social media pages.

After killing the five men, Ferrill turned the gun on himself.

He had worked as an electrician at the company for 17 years, the Milwaukee Journal Sentinel reported on Thursday.

A co-worker, who asked not to be named, told the outlet that Ferrill had been involved in a long-running dispute with one of the victims prior to the shooting.

Ferrill believed he was being discriminated against because he was black, the co-worker said.

The victim Ferrill had the ongoing dispute with had taken issue with the gunman frequently watching films on his phone during the workday.

Both Ferrill and that victim had also accused one another of stealing tools or tampering with their computer equipment.

Ferrill had been an electrician for 20 years after being honorably discharged from the U.S. Coast Guard where he served from 1987 to 1991.

Police were searching the three bedroom home where he lived with his wife and children on Thursday.
