OAKLAND, Calif. (KRON) — A longtime Peet’s employee was killed early Friday morning when the roof of a Peet’s Coffee distribution center in Oakland collapsed. A woman also suffered minor injuries in the collapse. The Peet’s facility was also used by other coffee companies.

On Friday evening, the victim was identified as 57-year-old Martin Gonzalez. He had been working at Peet’s Coffee for nearly two decades.

“We are all devastated by this tragedy,” Peet’s said in a statement. “The employee was a distribution lead and had been a beloved part of the Peet’s family for 17 years. Our thoughts and prayers are with his family.”

The facility was located in the 600 block of 85th Avenue. The building was described as a large distribution center for several coffee companies, according to Michael Hunt of the Oakland Fire Department. Approximately 20 firefighters responded to the incident. It was eased to Peet’s.

The distribution center is currently closed while the cause of the collapse is under investigation. The building has been red tagged so only emergency personnel and inspectors can enter.

The incident occurred at 3:13 a.m. on Friday just before the morning shift was set to begin, according to a Peet’s spokesperson. A 30-by-30-foot section of roof collapsed and killed the man, according to Hunt. The warehouse is located just south of RingCentral Coliseum.

Inspectors are working to determine if the roof collapse was weather-related.

More people could have been injured if the roof collapsed an hour later when the work shift changed, according to Hunt. The name of the person who died was not available early Friday.
