Cameron Robbins graduated from University Laboratory School in Baton Rouge in May and was on a sunset party cruise trip to the Bahamas with students from several local high schools.
According to witnesses at around 9:40 p.m, the 18-year-old — who was apparently acting on a dare — took a plunge off the party cruise into the ocean near Athol Island at night.
Robbins was last seen splashing in the dark, “shark-infested” waters a few feet from the boat, before vanishing from view.
A chaotic video was taken moments after the jump also shows the recent graduate ignoring onlookers’ pleas for him to grab a buoy.
The party ship, designed to resemble a pirate ship, remained in the area for several hours while the crew attempted to look for Robbins.
The Royal Bahamas Defence Force, assisted by the US Coast Guard Southeast, had been searching for the missing teen from the air, but so far without success.
The Coast Guard called off its own search two days later, after reportedly scouring over 325 square miles. Local officials now believe he may have met a grisly fate in the “shark-infested” area.
