Coach Tyler Wall, a fitness instructor who appeared in a MrBeast challenge video, died unexpectedly on February 18, 2025, in Greenville, North Carolina. His death certificate lists the manner of death as an accident, and the immediate cause of death as mitragynine toxicity. Mitragynine is a psychoactive compound found in the plant Mitragyna speciosa, commonly called kratom, which has opioid-like effects. This has led to speculation that his death was due to an accidental overdose of this substance. No official statement was made by his family about the cause of death, but it is understood that the MrBeast team consulted with them before releasing the video showing his involvement in the challenge. His passing deeply affected those he worked with, including the challenge participant Majd, who chose to continue the challenge in his memory.
