The identities of the seven presumed dead U.S. Marines and one Sailor were identified early Monday, along with an eighth U.S. Marine who died on the scene following an amphibious assault vehicle accident on Thursday.

The eight missing service members’ identities are as follows:

The ninth service member — who died on the scene and was the first reported casualty — was identified as
Lance Cpl. Guillermo S. Perez, 20, of New Braunfels, Texas. He was a rifleman with Bravo Company, Battalion Landing Team (BLT) 1/4, 15th MEU.

The eight missing service members were announced as presumed dead on Sunday at the conclusion of a 40-hour search operation.

“All eight service members are presumed deceased. The 15th MEU [Marine Expeditionary Unit] and the ARG [Amphibious Ready Group] leadership determined that there was little probability of a successful rescue given the circumstances of the incident,” I Marine Expeditionary Force said in a statement early Sunday.

Col. Christopher Bronzi, 15th MEU Commanding Officer, said “It is with a heavy heart, that I decided to conclude the search and rescue effort. The steadfast dedication of the Marines, Sailors, and Coast Guardsmen to the persistent rescue effort was tremendous.”

Nine service members lost their lives in the incident, as the presumed dead eight service members join one service member who was reported dead in the first reports of the incident.

16 service members were aboard the 20-ton Amphibious Assault Vehicle (AAV) when it sank during a training exercise off the coast of California on Thursday. Seven Marines were rescued alive, and one died on scene.

“I know all of us in the USMC family are extremely saddened following the announcement of the end of SAR operations. This difficult decision was made after all resources were exhausted. Our prayers continue to be with the family and friends of the 8 Marines and one Sailor we lost,” Marine Corps Commandant David Berger tweeted Sunday morning.

“Our thoughts and prayers have been, and will continue to be with our Marines’ and Sailor’s families during this difficult time,” Bronzi said. “As we turn to recovery operations, we will continue our exhaustive search for our missing Marines and Sailor.”

The Marine Corps are deploying offshore supply vessel HOS Dominator, as well as the Undersea Rescue Command and its Remotely Operated Vehicle (ROV) to survey the crash site and conduct recovery efforts.

The AAV had begun taking on water around 5:45 p.m. Thursday night and quickly sank. Two other AAVs were nearby and able to assist in rescuing the survivors and marking the location of the sunk vehicle.
