Brisyn Isaiah Gilmore was 15 when he was shot and killed in Tucson on the night of October 19, 2020. The shooting occurred at a party near Liberty Avenue and Pennsylvania Drive on the city’s south side after an argument between Brisyn’s group and another group at the gathering. Members of the opposing group reportedly fired handguns into the air, and as Brisyn and his friends tried to leave in an SUV-type vehicle the suspects fired on the fleeing car, striking Brisyn and a juvenile female companion.

The female sustained non-life-threatening injuries and was able to exit the vehicle and get to a family member who took her to the hospital. Brisyn and a friend were dropped off at Banner University Medical Center; Brisyn later died of his wounds. Officers who went to the party scene found no victims there but did recover multiple bullet casings on the property and in the street. No one from the vehicle remained at the scene and, at the time of the initial reports, no suspects were in custody.

Who has information about that night or about the people who fired on the departing vehicle?
