DESTIN — A man from Mobile, Alabama, apparently drowned Saturday at Crab Island, according to the Okaloosa County Sheriff’s Office.

A medical call was received about 4 p.m. about a person in possible cardiac arrest on a pontoon boat, a Sheriff’s Office news release said.

The victim, later identified as 36-year-old Essie Mitchell, was taken to Fort Walton Beach Medical Center, where the medical staff said he had water in his lungs. He was pronounced dead later and an autopsy will be scheduled.

Witnesses say Mitchell had gone down a slide into the water and was spotted a short time later floating face down in the water, the release said.

Most of the water at Crab Island is roughly 4 feet deep and fluctuates with the tide. However, strong currents and deeper water are nearby.
