About 6,000 to 10,000 revelers gather in their boats on a lake in Florida for the boozy Boca Bash on the last Sunday of April each year.

The party is an annual celebration on Lake Boca Raton, along Florida’s southeastern coast. The rave attracts people from near and far for the massive boating and drinking extravaganza.

The event sells no tickets, and guests are given few instructions – just show up, and remember a floaty.

The City of Boca Raton told Fox News Digital that it has no official involvement in putting on the party, but collaborates with community partners, like the Florida Fish and Wildlife Conservation Commission (FWC), to “ensure the safety of all attendees and protect our waterways.”

Marine units, along with a police helicopter, Ocean Rescue and the Coast Guard, began a search, but they were unable to find the 32-year-old, police said.

A swimmer later discovered Roselin at the bottom of the Intracoastal Waterway. The Boca Raton Police Department later announced that Roselin had drowned.

His girlfriend, Tamekia Rich, filed a wrongful death lawsuit against the City of Boca Raton, alleging negligence on the city’s part for failing to control the crowds and failing to provide adequate supervision of the water. The city countered, saying that it had not hosted the Boca Bash.

Revelers caught on camera dumping trash in water

Viral drone footage in 2024 captured two teenagers, 15 and 16, hefting two trash bins filled with bottles and other plastics over the railing of their fishing vessel as they sped away from the boozy gathering on April 28, 2024.

As the boat of partiers zooms away into the choppy waters of the Boca Raton inlet, the video pans out to the spread of debris left floating in their wake. Footage from the front of the boat shows the teens waving and laughing.

The video prompted outrage and the Boca Bash’s Facebook page wrote that they were “angered and disturbed by these actions.”

“Once the video was posted, we quickly got to work with the community to discover who the owner of the boat was and who was on the vessel in this particular instance committing an egregious act,” they wrote.

The two teens turned themselves in to police and face third-degree felony charges for causing pollution “so as to harm or injure human health or welfare, animal, plant or aquatic life or property,” the Miami Herald reported.

One of the boy’s parents issued an emailed statement to The Palm Beach Post through a spokesperson.

“We take responsibility for caring for our oceans and our community very seriously, and we are extremely saddened by what occurred last weekend at Boca Bash,” the family wrote. “We want to extend our sincerest apologies to everyone who has been impacted and rightfully upset by what occurred.”
