A student of Seth Rollins’ “The Black & The Brave Wrestling Academy,” which was featured on the WWE Network documentary chronicling his recent return, died last Thursday following a medical emergency at the facility.

ABC affiliate WKBW out of Buffalo, New York is reporting that 20-year-old Jonah Snyder was working out at the Moline, Illinois headquarters when he began feeling ill. According to Rock Island County Coroner Brian Gustafson, as Snyder’s condition got worse, he was asked by trainers to sit down. It was at that point a call was made to 9-1-1.

Paramedics arrived on location soon after the call was made to tend to Snyder, who had gone into cardiac arrest at the time of their arrival. Authorities are still looking into the situation as after autopsy results on Friday came back inconclusive.
