Autopsies for the three men who died running Sunday’s Detroit Free Press/Flagstar Marathon are complete, but it still isn’t clear what caused the deaths, according to the Wayne County Medical Examiner’s Office.
The office is submitting tissue and blood for further testing, including toxicology, before determining the cause and manner of the seemingly sudden deaths, officials there said. Those tests could take several weeks to finish.
“All three cases are pending,” investigator Val Knight said.
The men — Daniel Langdon, 36, of Laingsburg; Rick Brown, 65, of Marietta, Ohio, and Jon Fenlon, 26, of Waterford — died within a 16-minute span during the marathon in downtown Detroit.
Langdon collapsed on Michigan Avenue between the 11- and 12-mile markers at 9:02 a.m. Fifteen minutes later, Brown collapsed near the same spot.
The youngest victim, Fenlon, collapsed at 9:18 a.m. just after finishing the half-marathon in 1:53:37.
The marathon is an annual event in its 32nd year. The only other fatality recorded during the event was in 1994 when a 42-year-old runner died of a heart attack.
