The Masquerade nightclub in Underground Atlanta is the target of a negligent security lawsuit lodged over the death of a 21-year-old who was shot there.

Ewell Ynoa died while attending a concert on Nov. 12, 2017, where Stephen Goss, also known as “Cousin Stizz,” was performing. According to a lawsuit filed in DeKalb County State Court Friday, at about 9:30 p.m. that night, “a deranged, armed assailant entered one of the confined, crowded venues with a handgun, and shot four persons inside the concert, killing two people—including Ewell Ynoa.”
