A divided Delaware Supreme Court on Wednesday upheld the death sentence of a former Air Force staff sergeant who killed his wife to collect on a $100,000 life insurance.
Gary W. Ploof was convicted of shooting his 29-year-old wife, Heidi, to death in November 2001 in the parking lot of the Dover Wal-Mart. At trial, Ploof claimed his wife had committed suicide, and he tried to make it look like a homicide to spare her reputation.
