A stuntman on The Walking Dead has died after a tragic injury on the set. John Bernecker suffered terrible injuries when he fell more than 20 feet and landed on concrete and filming on the hit TV show was halted. Bernecker was a veteran stunt performer and fight choreographer. According to his IMDB page, he has worked on projects such as Olympus Has Fallen, The Hunger Games: Catching Fire and Mockingjay Parts 1 & 2, and Logan among many others.

The accident happened on Wednesday and he was rushed to Atlanta Medical Center, where he later died. Richard Hawk, a coroner for the Coweta County Coroner’s Office told Fox 5 Atlanta that the cause of death was blunt force trauma. Bernecker was an experienced and skilled stuntman with a long list of movie credits.

Stuntwoman Janeshia Adams-Ginyard said: “Very skilled, he knew his stuff because he helped me with camera angles where to hit and punch if the cameras were in a certain spot.” Stuntman Diego Ward added: “People don’t think about the stunt guys until something like this happens, but there are a lot of risks with the job.”
