Coast Guard search parties scouring the Pacific for 12 missing Marines who vanished after a tragic helicopter collision have found four inflated life rafts. Unfortunately, rescue teams have yet to locate a single survivor.

Last Friday, two CH-53 helicopters carrying six people each crashed in midair off the coast of Oahu, Hawaii during a nighttime training mission. The military immediately dispatched search parties to find the missing Marines, but turbulent waves and suspicious laser pointers hampered the investigation the entire weekend. The fifth day of searching is underway, but hope is not dwindling.

By Monday morning, the Coast Guard had conducted 89 searches across 24,000 square miles. Spokesmen said that the Coast Guard was assuming the best-case scenario that the missing Marines had the equipment and fortitude to survive.
