A 48-year-old New Hampshire man died while diving off Duck Key Wednesday afternoon, the Monroe County Sheriff's Office says.
Matthew Prior was on a dive trip with his family aboard a vessel named the Seafari
. Deputy Becky Herrin said that according to witnesses, Prior and others were diving on a hooka rig and he'd been underwater about 15 minutes.
A dive instructor underwater with Prior told deputies that Prior indicated several times he was alright before signaling he wanted to surface. As he was surfacing, Prior suddenly became unresponsive, Herrin said.
The instructor grabbed him, took him to the surface and called for help. Cardiopulmonary resuscitation was started when Prior was put back on the boat, which then headed back to shore.
Prior was pronounced dead at Fishermen's Hospital. An autopsy will be done to determine the cause of death.
