On Sunday, June 25, 2006, Mauricio DeHaro, 32, was fatally wounded during a shooting at the Safeway distribution center in Denver. DeHaro, a married father of two who had worked at the warehouse for six years, was among the victims when coworker 22-year-old Michael Julius Ford began firing a .357-caliber revolver and set several small fires inside the facility. About 152 employees were on duty that afternoon; four other Safeway employees and a Denver police officer were also injured.

First 911 calls came in around 3:00 p.m., triggering a large police response and a more than hour-long search of the complex by SWAT teams. Officers were ambushed at one point, returned fire, and shot Ford, who died at the scene. Investigators were unable to establish a clear motive. Ford’s sister alleged he had been targeted at work for his Muslim faith, a claim disputed by his father, Safeway officials, and a wounded coworker; his father also suggested possible anger over a missed promotion, which the company denied.

Did anyone who worked at the Denver Safeway distribution center in 2006 notice tensions or incidents that might shed light on what happened that day?
