Sea Dog, Pompano Bch, Capt Dan-115' to bottom. BT 9 min. About 9 minutes into dive a 54 year old hard core experienced female diver 1000+, didn't feel well at depth and started accent on the anchor line tied into wreck, about 10 seconds up suffered a heart attack and became unconscious and not breathing, reg half in and half out of mouth, reg was held in place and head tilted back and surfaced with assistance Thanks to the dive master Mackenzy who went above and beyond with relentless CPR on her, with great sadness she didn't make it and will be missed by many, she was my dive buddy for 10 years.
