Authorities have called off the search for Maeve Kennedy Townsend McKean and her 8-year-old son, Gideon Joseph Kennedy McKean, who went out in a canoe on the Chesapeake Bay Thursday and didnt return to shore .

This was a difficult case, and even more difficult to make the decision to suspend the search, Cmdr. Matthew Fine of the U.S. Coast Guard said late Friday, according to CNN . Our crews and partners did everything they could to find them. Weve kept the family informed at every step during the search, and our thoughts are with them tonight.
