BUZZARDS BAY, Massachusetts (CNN)  -- A crew member aboard a freighter seized by pirates off east  Africa said Wednesday that the crew had captured one of four pirates who hijacked their vessel, but they released him in a failed hostage trade. Shane Murphy is one of the crew members on board the U.S. ship that was hijacked off Somalia's coast. The crew of the U.S.-flagged Maersk Alabama had hoped their release of the pirate would lead the pirates to release Capt. Richard Phillips, but it did not, crew member Ken Quinn told CNN in a satellite telephone call. Instead, the four pirates -- who had scuttled their boat when they boarded the ship armed with AK-47s -- took Phillips with them aboard the ship's 28-foot lifeboat, Quinn said.
