Eric Johnson Jr., 38, was shot and killed backstage at Shoreline Amphitheatre in Mountain View, California, on August 22, 2014. The shooting occurred as the Wiz Khalifa concert on the Under the Influence tour was ending. Reports say Johnson was involved in an altercation with the shooter; despite security being present, the gunman escaped and no murder charges were filed.

Investigators detained several witnesses for questioning, and a rifle was later found on rapper Jeezy’s tour bus; he was arrested on an illegal possession charge that was subsequently dropped. Johnson’s family described him as a peaceful person and later filed a wrongful death suit against Live Nation alleging inadequate security. In 2015 the California Court of Appeal ruled Live Nation was not responsible, finding the violent attack was not a foreseeable occurrence the promoter could reasonably have prevented.

Who in the audience or backstage that night might have seen the shooter or the altercation and not yet come forward?
