Derrick Russaw, an 18-year-old from Orlando, Florida, was fatally shot on January 6, 2017. He was found on the roadway in the 4800 block of South Texas Avenue and was taken to Orlando Regional Medical Center, where he was pronounced dead. The Orange County Sheriff’s Office identified him and treated the killing as a drive-by shooting.

Investigators identified four suspects — three juveniles and one adult — but the State Attorney’s Office declined to file formal charges, and no arrests or prosecutions followed. The community held a candlelight vigil in his memory; that event was later disrupted when a separate drive-by shooting injured two people. Few details about motive or the shooters have been released.

Did anyone who knew Derrick at Oak Ridge High School or in the neighborhood see or hear anything on January 6, 2017, that could help investigators?
