Searchers who recovered three bodies after a helicopter crash off the Alabama coast suspended their search for a fourth man, the U.S. Coast Guard said. "The decision to suspend the active search was terribly difficult," UPI quoted Coast Guard Commander Capt. Donald J. Rose as saying. "We saturated 95 percent of Mobile Bay for nearly two days with both aircraft and boats to thoroughly cover the search area. Now, we must shift our focus to continuing salvage and recovery operations. As we continue to recover wreckage, we will look for the missing crewman." It had not been determined what caused the Coast Guard MH-65C "Dolphin" helicopter to go down Tuesday night while on a mission from the Aviation Training Center at Mobile Regional Airport. The bodies of the three other crew members were recovered, including two found Thursday.
