The wreckage of a military helicopter that was reported missing on Wednesday morning was found in a national forest outside of San Diego, but it is not clear whether there are any survivors.

The wreckage of the CH-53E Super Stallion helicopter was discovered in Pine Valley, California, according to the 3rd Marine Aircraft Wing, and was believed to have carried five Marines on board. It departed from Creech Air Force Base in Nevada on Tuesday evening and was bound for Marine Corps Air Station Miramar in California.
