“Deep sorrow today, and for every tomorrow,” wrote Jeffrey Dean Morgan in an emotional post. “Love, respect, and condolences to John’s family, and friends. He will be forever missed.”
Jordan Woods-Robinson also shared his condolences. “Can't stop thinking about John Bernecker. All of my love and hopes for solace goes out to his loved ones and our community,” he wrote on Twitter.
Ann Mahoney, who exited the show in its seventh season, also took to social media, writing, "Much sadness about #nola actor #JohnBernecker today. Sending peace to his family. Pray for them please."
Bernecker reportedly suffered head injuries after falling over 20 feet onto a concrete floor, but apparently missed the safety cushion “by inches,” according to TMZ.
"We are saddened to report that John Bernecker, a talented stuntman for The Walking Dead and numerous other television shows and films, suffered serious injuries from a tragic accident on set," AMC told ET in a statement on Thursday, prior to news of the stuntman's death. "He was immediately transported to an Atlanta hospital and we have temporarily shut down production. We are keeping John and his family in our thoughts and prayers."
ET has learned that OSHA launched an investigation on Friday into the death of Bernecker, which is believed to be the first stunt-related death in the United States in more than 17 years.
According to Michael D’Aquino, a spokesman for the OSHA regional office in Atlanta, Georgia, the OSH Act requires the agency to complete its investigation within six months, but “that doesn’t necessarily mean it will take that long.”

Our thoughts and prayers are with the performer and his family."
Bernecker had a prolific career as a stuntman, which included working on films such as 22 Jump Street, The Fate of the Furious, This Is The End, The Hunger Games: Mockingjay - Part 2, Get Out, Logan, as well as the upcoming Marvel movie, Black Panther.
Additionally, Bernecker's IMDb page had him listed as performing stunt work on Dwayne "The Rock" Johnson's upcoming movie, Rampage, which is still in production.
