Juan Guerra was 24 when he was shot and killed in West Oakland on September 16, 2009. His death came during a violent year for the city: Oakland recorded 104 homicides in 2009 amid a spike in gang activity, drug-related violence, and retaliatory shootings.

Police at the time reported some leads and witnesses in the area, but investigators faced limited resources and trouble securing community cooperation, and no substantial progress in capturing suspects in Guerra’s case was reported. The killing is one of many from that period that underscores the broader challenges the city faced with gun violence and scarce community resources.

If anyone knew Juan, was in West Oakland that evening, or has information that could help solve this case, please come forward.
