After five days without finding any survivors, the Coast Guard is suspending suspended its search for 12 Marines who have been were missing since Thursday Jan. 14 when their two CH-53 helicopters crashed off Oahu.

"The decision to suspend the search without finding survivors was particularly difficult," said Capt. James Jenkins, commander of the Coast Guard's 14th District.

Searchers have discovered some of the wreckage from the helicopters on the ocean floor about two miles offshore in roughly 325 feet of water, Jenkins said at a news conference Tuesday in Hawaii. The Marine Corps will now be in charge of the investigation into what happened and any possible recovery operations, he said.

"I know that nothing can ease the pain of the families of those missing, but I hope that the [search] efforts and the knowledge that so many were willing to put forth so much effort to try to bring those Marines home will provide some solace in the future," Jenkins said.
