The War at Home (S04E02)

A 2004 case in which an Iraq War veteran abruptly disappeared is reopened after the missing woman's prosthetic arm is found in the Delaware River. The probe reveals that the victim lost her arm during an attack in Iraq and felt responsible for the death of a friend killed in the ambush. The woman's husband becomes a leading suspect, but he claims he loved his wife, even though she came back from the war a much changed person. (CBS TV Network)
