Man Finds Brick Of Unknown Substance In Water Near Marathon, Fla., Sniffs It And Dies

A 53-year-old Florida man died after allegedly snorting a mystery substance he found floating in the water on a fishing trip with his brother.

The bobbing brick allegedly resembled a kilo of cocaine and Thomas Swindal was seen inhaling some of it shortly after the brothers pulled it on deck, WPBF reported.

They continued fishing, but 90 minutes later Swindal's behavior abruptly became dangerous and strange, even for a person high on nose candy.

His brother Kenneth claimed to Monroe County sheriffs that Thomas ran around the boat and tossed things like a cell phone and a VHF radio overboard.

Swindal also removed the engine's cowling and dropped it into the water and ultimately damaged the engine so that it wouldn't start, the sheriffs said in their report.

Kenneth claims he threw all sharp objects and the phantom drug overboard to protect his brother from hurting himself, according to Florida Today.

A passing vessel came to their aid when Kenneth flagged it down and Thomas was taken to one hospital, before being transferred to another in Miami where he died, WPBF said.

Officials are awaiting the results of an autopsy to find out what killed Swindal.
