Early reports from the St. Croix Source indicate that Dr. Guy Garman, known as "Doc Deep" to the technical diving community, died on Saturday while attempting to break the world record for deepest scuba dive.

Garman's plan was to descend to a depth of 1,200 feet off the coast of St. Croix on Saturday, August 15th, exceeding the current record of 1,090-feet set by Ahmed Gabr in 2014.

A social media post reported that everything was going to plan as he and his support team (along with his son) reached the 200-foot mark, where he continued descending solo. Thirty eight minutes later, he was expected to have reached the bottom of his dive and ascend to the 360-foot mark, where a separate support team was waiting for him, but he never arrived.

Garman was attached to a 1,300-foot weighted line, and plans are being made to retrieve his body within the week to help explain the cause of the accident.

Garman had been preparing for this dive over the past two years with the help of a 28-person support crew, medical professionals and three boats.

Scuba Diving magazine recognizes this historic attempt for the technical diving community, and sends condolences to his family and friends.
