Man says son who died in Afghanistan allegedly killed by fellow US Marine

The father of a U.S. Marine killed in Afghanistan says he was devastated to learn that a fellow Marine was allegedly responsible.

David Mundo Santos is quoting a military representative who carried the news of Cpl. Dave M. Santos' death as saying another Marine is accused in the fatal stabbing.

The Department of Defense said Monday that the 21-year-old Santos died Friday in Helmand province. He was assigned to 2nd Battalion, 6th Marine Regiment, 2nd Marine Division based at Camp Lejeune, N.C.

In its announcement, the DOD only said the death is under investigation.
