Rock singer Marilyn Manson chose a shocking prop to include in his performance Sunday night during Ozzfest Meets Knotfest in San Bernardino, California.

Confined to a wheelchair due to a September stage prop accident that left his fibula shattered, the singer performed his single "We Know Where You F------ Live" while wielding a fake rifle and pretending to shoot bullets into the crowd. Footage surfaced by TMZ showed the rocker dressed in a hospital gown singing into a microphone attached to the spoke of the weapon.

Manson's performance came just hours after gunman Devin Patrick Kelley stormed a local Texas church and opened fire, killing 26 people. San Bernardino was also the place of a previous attack that left 14 dead nearly two years earlier when Syed Rizwan Farook and Tashfeen Malik attacked an office holiday party in December 2015.

Mansion has not shied away from controversial moments throughout his 30-year-career - his self-proclaimed title of "Antichrist Superstar" being one of them. His Sunday performance marked his return following his on-stage accident. Recent news of the shock performer also surfaced when long-time bassist Twiggy Ramirez was fired from the band following sexual harassment allegations, and guitarist Daisy Berkowitz died of colon cancer in October.
