St. Maarten police have arrested a second suspect in the slaying of an American couple who were stabbed to death in their beachfront condominium.

A statement by prosecutors on Monday identifies the 17-year-old suspect by his initials, J.C.M. It says he was captured after an intensive search. Authorities say more arrests "cannot be excluded."

Earlier this month, police also arrested Meyshane Johnson, a Jamaican security guard. He is being held on pre-trial detention as prosecutors build their case.

His lawyer says he denies killing the couple.

Michael and Thelma King of Mount Pleasant, South Carolina, were found stabbed to death in their vacation home last month.

Friends say the Kings were part-time residents of St. Maarten. Michael King was planning on starting a rum business on the tiny Dutch territory.
