The Coast Guard received a report from a woman at around 6:30 p.m. Wednesday saying her husband and two others went kayaking and did not return at their planned time of 4:30 p.m.

One of the searchers found a kayaker clinging to an overturned kayak around 8 p.m. Authorities say she was hypothermic and unable to speak. She was taken to Eastern Maine Medical Center. Her condition wasn't immediately known.

A second kayaker was found unresponsive about 30 minutes later. He was taken to Prospect Harbor and pronounced dead. The third was later found unresponsive and declared dead.

The Coast Guard is investigating.
