On April 19, 1995, Timothy McVeigh, an ex-Army soldier parked a rented truck in front of the Alfred P. Murrah Federal Building in downtown Oklahoma City and detonated it at 9:03am, killing 168 people including 19 children. He was executed for the crime on June 11, 2001.
At the time of the bombing, Tom Hall was working for the General Services Administration (GSA) as a construction planner estimator on the first floor of the Alfred P. Murrah Federal Building. He was severely injured by the bombing but recovered and returned to work for the GSA until he retired in 2015.
Tom served on the Memorial Design Selection Committee and played a role in choosing the final design for the memorial.
