Grigory Nekhoroshev, a Russian journalist living in exile in Latvia who had exposed Putin's secret affair with an Olympic gymnast, died at age 69 after eating poisonous mushrooms — reported as accidental. Multiple outlets confirm his death and his role as a Putin critic, though the circumstances remain difficult to verify independently given the location and lack of official investigation detail. The main uncertainty is whether the poisoning was genuinely accidental or deliberate, which cannot be determined from available reporting.
