While Damageplan was promoting the album at a concert on December 8, 2004, a former U.S. marine named Nathan Gale climbed on stage and murdered Darrell, two members of the band's crew, and a local concert goer. Although no motive was found, some witnesses claimed Gale blamed the brothers for Pantera's breakup and believed that they had stolen his lyrics. Gale was killed by police officer James Niggemeyer, who was found to have acted accordingly by the Franklin County prosecutor's office. The band's manager confirmed there are unreleased Damageplan recordings, although they have not surfaced, and the band has not performed since the incident. Abbott and Zilla have joined the band Hellyeah, and Lachman joined The Mercy Clinic.
