A Colorado man, 69, died Friday afternoon after he was pulled from waters off Allerton Beach, according to Kauai police.

Kauai police said first responders were dispatched to the beach about 1 p.m. Friday for a call about a man who struck his head on a rock while boogieboarding.

Allerton Garden security guards, Kauai Fire Department rescuers and paramedics pulled the man out of water from the remote beach. AMR paramedics performed advanced life support but were unsuccessful in resuscitating the man who was pronounced dead at the scene.

His identity was not immediately released.

An autopsy is pending to determine the man’s exact cause of death, but foul play is not suspected, police said.

Life’s Bridges Hawaii volunteers are assisting the victim’s family.
