A toxicology report has determined that American chess grandmaster Daniel Naroditsky died from cardiac arrhythmia last October, ruling the 29-year-old’s death accidental. The findings bring closure to a case that initially raised questions about the circumstances surrounding the chess star’s untimely passing.
The report from the North Carolina medical examiner’s office indicates Naroditsky died from probable cardiac arrhythmia caused by an inflammatory disease affecting his organs. While methamphetamine, amphetamine, and the plant-based supplement kratom were found in his system, the report lists these substances as contributing factors rather than primary causes of death.
Significantly, the toxicology analysis revealed that drug concentrations in Naroditsky’s system were at levels considered non-toxic and non-lethal. The medical examiner’s findings explicitly state there is no evidence of intentional or unintentional overdose on illicit, prescription, or over-the-counter substances.
Naroditsky was found dead at his home in Charlotte, North Carolina, in October. Police initially investigated the death as a potential overdose or suicide. However, the postmortem examination revealed no evidence of injury, and no suspected illicit substances or paraphernalia were present at the scene when friends discovered him.
According to the medical examiner’s report, friends had observed concerning behavior from Naroditsky in the days preceding his death. He appeared to exhibit altered mental status while streaming online, prompting friends to visit his home and remove approximately 40 pills believed to be the stimulant Adderall.
The report notes that Naroditsky had been experiencing significant stress in the weeks before his death due to cheating allegations made by former world champion Vladimir Kramnik. Naroditsky denied these allegations, which were never proven. The international chess governing body announced in October it was considering disciplinary action against Kramnik for making the accusations.
Naroditsky had established himself as both a competitive chess player and a popular online personality, credited with helping expand the game’s audience through his streaming activities. His accomplishments in the chess world were notable from an early age. At 14, he published “Mastering Positional Chess,” demonstrating the depth of his understanding of the game. He competed in five U.S. Championships throughout his career.
The Drug Enforcement Administration has noted that kratom, one of the substances found in Naroditsky’s system, can lead to psychotic symptoms and psychological and physiological dependence, though the report emphasizes the levels found were not toxic.
This case underscores the complex interplay between physical health conditions, stress, and substance use. The medical examiner’s conclusion that Naroditsky’s death resulted from a cardiac condition rather than drug overdose provides important clarity for his family, friends, and the chess community that mourned his loss.
