RICHMOND, Va. (AP) — A state investigator who examined the events leading to an attack on a Virginia state senator by his son has resigned, complaining that his superiors interfered with his work and made him tone down his report, according to a letter of resignation released Tuesday.

G. Douglas Bevelacqua, director of the Division of Behavioral Health and Developmental Services with the Office of the Inspector General, said his report has been subject to revisions to tone down his findings on the Nov. 19 knife attack on Sen. Creigh Deeds by 24-year-old Austin “Gus” Deeds at their rural homestead in Bath County.
