Earlier this week, Joel Taylor – the star of Discovery Channel reality show Storm Chasers – passed away following a suspected overdose.

The 38-year-old was found dead in his cabin when the Royal Caribbean Cruise Line Harmony of the Seas cruise ship he was travelling on docked in San Juan, Puerto Rico on Tuesday.

“It appears the death could be an overdose and Joel Taylor was consuming controlled substances,” a law enforcement source told TMZ.

Passengers on the ship claimed that drugs on the party boat were “plentiful”, and a representative for the boat confirmed that Joel was found unresponsive in his cabin on Tuesday.

There was a big party on board the ship on Tuesday, with performances from Olivia Newton-John and DJ duo Galantis.

But now, TMZ reports that the FBI have launched an investigation into the circumstances surrounding Joel’s death.

The site has claimed that “huge quantities” of “party drugs” were on-board, including ecstasy, cocaine, and GHB.

The FBI reportedly want to know how the illegal substances made it onto the ship, and how they were distributed after the cruise set sail.

Royal Caribbean International’s website clearly prohibits the possession of illegal substances on their ships.

“These and other similar items will be confiscated upon being found. Alcoholic beverages, illegal drugs, flammable liquids, explosives, and dangerous chemicals will not be returned,” guidelines read.

An autopsy for Joel is still currently underway to determine the cause of death.

He joined the cast of Storm Chasers back in 2008, but the show was cancelled in 2012.

The star recently welcomed his first niece on 15 January, and had posted the news on his social media.
