“It saddens me to share that today we found Matthew. He was located this morning in Chatham. He had crawled into an airtight space on a boat for shelter from a recent storm, and fell peacefully asleep and ran out of oxygen. This, of course, was not the ending we wished or hoped for,” wrote Runci.

The 44-foot motor lifeboat was not in the water but was on display on the lawn at Coast Guard Station Chatham.

A Coast Guard spokesman says the boat was retired in 2009 after 46 years of service.
