Anthony Ferrill

Molson Coors has confirmed social media rumors that a noose was once placed on the locker of Anthony Ferrill, the 51-year-old African-American man who shot and killed five coworkers before taking his own life.

“It was a disgusting act five years ago, and remains disgusting today,” Molson Coors spokesman Adam Collins said in a statement reported by CNN. “Our HR team notified him of the incident. It was investigated fully. No camera footage was available to show who placed it on the locker, we offered HR and Security services to the employee, we talked to the brewery leadership team in Milwaukee about the issue and we ensured everyone knew about our confidential paths to share discrimination or harassment complaints.”

Not long after the shooting, many people posted on social media that racial harassment may have been behind the shooting.

The victims were identified by police as Jesus Valle Jr., 33; Gennady Levshetz, 61; Trevor Wetselaar, 33; Dana Walk, 57; and Dale Hudson, 60. They were electricians, powerhouse operators and machinists at the facility, according to Molson Coors CEO Gavin Hattersley.
