A Florida man is dead and despite a medical examiners report, relatives believe he died from a flesh-eating virus.

Cason Yeagar, 26, died Tuesday in Leesburg. The Lake County Medical Examiner says he died of natural causes, but friends and relatives think the flesh-eating virus known as Vibro vulnificus somehow got into his system when he was on the Weeki Wachee River last week.

But people enjoying the river on Friday weren't concerned.

"Everything that I've heard up to this point has been due to warm water out in the Gulf," says Rob Oppedisano. "The river is moving, there's good flow. I feel pretty good so far." 

The Florida Department of Health says nine cases have been reported and of them, three people have died. None of them are in Lake County.
