Also killed in the shootings were Erin Halk, 29, a club employee who loaded band equipment; fan Nathan Bray, 23; and Jeff Thompson, 40, who was affiliated with the band.
Two others were hospitalized. The nature of their injuries was not disclosed.
The guitarist's brother, Vinnie Paul Abbott, the drummer for Damageplan, was rushed to safety offstage and tearfully tried to learn his brother's fate from officers who couldn't even tell him which hospital he was taken to.
