SOUTH PORTLAND, Maine (NEWS CENTER) -- The U.S. Coast Guard is trying to find the person who's suspected of making more than a dozen fake distress calls over the past three years.  Lieutenant Nick Barrow said the Coast Guard has spent more than 50 hours and $188,000 responding to the calls.

Barrow said the Coast Guard has used its new Rescue 21 Radio System to track the approximate location of the calls, which came in over VHF radio, and they appear to be from the Lincolnville area. The caller, who is male, never gives his location in the call and never responds to calls back from the Coast Guard.

He tends to call during the third week of the month, in the middle of the week, between 3 p.m. and 5:30 p.m., though not every call has fit that pattern.
