BOSTON >> A Massachusetts man has pleaded guilty to making hoax radio distress calls to the Coast Guard that prompted fruitless searches that wasted time and resources.

Prosecutors say 47-year-old Roger Martin, of Fairhaven, made three calls to the Coast Guard in April and May 2015 claiming that he was on a boat on Cape Cod Canal that was sinking.

In each case he provided another man's name, address, and on one occasion, even birth date, that he had obtained improperly from a law enforcement database while working as a dispatcher for the Bristol County Sheriff's Office.

Martin pleaded guilty this week in federal court to three counts of sending false distress messages and one count of identity fraud. Sentencing is scheduled for Nov. 22.
