One Marine who served on the 15th MEU, I Marine Expeditionary Force, was pronounced dead at Scripps Memorial Hospital La Jolla. Two others suffered injuries and were transported to local hospitals, where one was listed in critical condition and the other in stable condition. A total of eight people were recovered from the AAV, while another eight were confirmed missing in the waters. Search and rescue efforts immediately began by the Marines with help from the U.S. Navy and Coast Guard. "We are deeply saddened by this tragic incident. I ask that you keep our Marines, sailors, and their families in your prayers as we continue our search," Bronzi said in a statement. According to the United States Naval Institution, the AAV has been the "primary infantry sea-to-land transport vehicle since the 1970s," and the Marines are currently testing its replacement.
