Cameron Robbins, an 18-year-old recent graduate from Louisiana was celebrating his high school graduation on a sunset cruise in the Bahamas when he jumped off the ship after allegedly being dared. 

The U.S. Coast Guard's multi-day search for Robbins has been called off and his family said they were returning to Baton Rouge. 

In a video shared on social media, Robbins can be seen swimming in the water while his friends record from the balcony above. It's hard to tell but the video appears to capture a shark following Robbins through the water. 

Robbin's family released a statement tanking "well-wishers for granting us the privacy we need to properly remember our son and mourn his loss."
