Summary: The Army began an investigation after being prodded by Amanda Henderson, wife of Sgt. 1st Class Patrick Henderson, an Iraq combat veteran who spent the final months of his life as an Army recruiter before hanging himself with a dog chain in his backyard shed. In all, 15 of the Army’s 8,400 recruiters have committed suicide since 2003, with more than 540 of the Army’s half-million active-duty soldiers killing themselves.
