Carnival Cruise Lines says a 6-year old boy has drowned in one of its pools while at sea.

The company says in a statement that the Carnival Victory ship was on the last leg of a four-day Caribbean cruise on Sunday when the boy drowned. He was at the pool area with other family members.

The ship arrived at the Port of Miami this morning.

The Miami-Dade Police Department is investigating and identified the boy as Qwentyn Hunter of Winter Garden, FL. Investigators say the boy was with his 10-year old brother in the pool at the time. Passengers immediately pulled the boy from the water and began CPR, but the child was pronounced dead at the scene.
