A November 2017 rap concert at the Masquerade in Underground Atlanta ended in deadly violence when 22-year-old Giovan Diaz was shot during an onstage confrontation. Diaz and a friend, 21-year-old Ewell Ynoa, had recently moved to Atlanta to pursue work in entertainment and climbed onto the stage during an intermission for rapper Cousin Stizz. Another concertgoer, Jonathan Bautista, objected to their presence; an argument followed and Bautista produced a pistol and opened fire, fatally wounding both Diaz and Ynoa and wounding two others before fleeing the scene.

Atlanta police later identified the shooter and arrested 25-year-old Jonathan Bautista, charging him with two counts of murder. A civil trial over security at the venue was later brought by the families; a jury found Sony Music Holdings and others liable for inadequate security and awarded damages to the families of Diaz and Ynoa.

Does anyone who attended that night or knew Giovan want to share memories or information that could add context to what happened?
