Six-year-old Qwentyn Hunter drowned on Sunday, October 13 in one of the pools on a cruise ship he was riding on with his family.

According to officials from Carnival Cruise Lines, the boy had been on a four-day Caribbean cruise with his family and their company’s “CareTeam is [currently] providing assistance and support.”

The ship reached Miami shores on Monday, October 14. The pool was already closed, and police had already sealed its perimeters with crime scene tape while officials took photographs of the area.

An investigation from the Miami-Dade police showed that Hunter was swimming in the pool with his 10-year-old brother when he drowned at around 4:45 p.m. while the ship was out at sea.

The boy was immediately given cardiopulmonary resuscitation after being pulled from the water but was already dead.
