Rogerio Nathaniel Warrick was 22 when he was killed in Oakland, California, on August 2, 2013. His death occurred during a year of unusually high violence in the city, which recorded 92 homicides in 2013.

Warrick’s killing was one of many that year as Oakland struggled with gang violence, socio-economic disparities and an overstretched police department. The Oakland Police Department was described as understaffed, with a homicide clearance rate well below the state average, and many cases from 2013, including Warrick’s, remained unsolved at the time.

Does anyone who knew Rogerio Nathaniel Warrick or who has information about what happened on August 2, 2013, have details to share with investigators?
