The parents of a U.S. soldier who killed himself after returning home from military duty in Iraq have sued the U.S. government for negligence. Joyce and Kevin Lucey say their son Jeffrey hanged himself after the U.S. military ignored his depression. In late May 2004, Jeffrey was involuntarily committed to a military veterans hospital after he ignored his family’s pleas to seek help. The hospital discharged him after a few days. He killed himself three weeks later. His father came home to find his son had hung himself with a hose in the cellar of their house. The dog tags of two Iraqi prisoners he said he was forced to shoot unarmed lay on his bed. The Lucey suit follows another case in which two veterans’ rights groups say the Department of Veterans Affairs delayed and denied veterans help for disabilities such as post-traumatic stress disorder.
