Lance Cpl. Armando Ortiz Canseco, a 21-year-old Marine stationed in San Diego, vanished from the amphibious transport dock ship USS Anchorage in the early morning hours of June 25 during a training exercise off the Southern California coast. Two days later, the Marine Corps declared him dead.
Four branches of the military, the Navy, Marine Corps, Coast Guard, and Air Force, threw everything they had at finding him. They searched roughly 2,400 square miles of ocean, deployed three surface ships and 12 aircraft, and still came up empty.
By June 26, officials shifted from search and rescue to recovery operations. On June 27, 2026, Canseco was officially declared deceased. The Marine Corps publicly identified him the following Monday. The circumstances surrounding his disappearance remain under investigation, and officials have offered no explanation for how a young rifleman went missing from a warship in the middle of a training exercise.
Canseco enlisted in April 2023. He completed recruit training, earned his designation as a rifleman, and joined 2nd Battalion, 4th Marine Regiment at Camp Pendleton. He was assigned to the USS Anchorage as part of the 13th Marine Expeditionary Unit and the Makin Island Amphibious Ready Group when he disappeared.
He was 21 years old. He came from Minnesota. He held the Marine Corps Good Conduct Medal and the Sea Service Deployment Ribbon, awards that speak to a clean record and time at sea.
None of that tells us what happened to him.
Col. Richard Alvarez, commanding officer of the 13th Marine Expeditionary Unit, issued a statement:
"On behalf of the Marines and Sailors of the 13th Marine Expeditionary Unit, I extend our deepest condolences to the family and loved ones of Lance Cpl. Ortiz Canseco. He earned the title of United States Marine and served his country with honor and commitment. We mourn alongside his family, and we remain committed to bringing him home."
Capt. Gary A. Harrington, commodore of Amphibious Squadron 7, said Canseco's loss was felt "deeply across our entire Navy-Marine Corps team."
Harrington added:
"The amphibious Navy exists to fight alongside the Marine Corps, and a loss to the Marine Corps family is a loss to our own."
Those are the right words. But words do not answer the questions that matter most to Canseco's family and to the public that funds and trusts these institutions.
The Marine Corps has not disclosed the type of training exercise underway when Canseco vanished. Officials have not said what specific body of water the USS Anchorage was operating in beyond "off the Southern California coast." They have not said whether any remains or personal effects were recovered. They have not named a cause of death. They have not described the circumstances of his disappearance in any detail.
An investigation is open. That is all we know.
A man does not simply vanish from a Navy warship without a sequence of events that someone, somewhere, can reconstruct. Modern amphibious transport docks carry extensive surveillance, monitoring, and watch-standing protocols. The fact that the military mobilized four service branches and scoured 2,400 square miles of ocean suggests they took this seriously. The fact that they found nothing suggests the ocean took Canseco quickly and completely.
Back home, loved ones and family members gathered Sunday night at Oak Grove Lutheran Church in Richfield for a vigil. A 21-year-old who left Minnesota to serve his country will not be coming back the way anyone hoped.
Canseco's story is not, at this point, a story of institutional failure or policy breakdown. It may become one, depending on what the investigation reveals. For now, it is something more basic and more painful: a young American volunteered for dangerous work, trained for it, deployed for it, and died in the course of it before he turned 22.
The military owes his family, and the country, a full, honest accounting of what happened aboard the USS Anchorage in those early morning hours. Condolence statements are necessary. Transparency is not optional.
Americans who raise their children to serve deserve to know, with specificity, what went wrong when one of them doesn't come home.
