A memorial service will be held for two FBI agents and a District of Columbia police sergeant who were shot and killed 20 years ago inside the headquarters of the Metropolitan Police Department.
On Nov. 22, 1994, a lone gunman walked into a third-floor squad room, where he opened fire with an assault weapon.
He fatally shot FBI agents Martha Dixon-Martinez and Michael John Miller, and Metro police Sgt. Henry "Hank" Daly.
The gunman, Bennie Lee Lawson, killed himself.
The week before the shooting, Lawson had been questioned as a suspect in a triple homicide.
A memorial service for Daly and the slain FBI agents will be held at 9 a.m. Friday at St. Patrick's Church in Northwest D.C. A wreath-laying ceremony will follow at the National Law Enforcement Officers Memorial.
