Just months ago, 70-year-old Dr. Frank Meza finished the Los Angeles Marathon.
It would have been a record-beating time for his age group: 2 hours, 53 minutes and 10 seconds.
On Thursday he was found dead in the Los Angeles River under a bridge about a mile from Dodger Stadium.
His death came just days after race officials threw out his result over allegations that he'd cheated.
According to CNN, Dr. Meza denied the allegations.
