On Palm Sunday, April 13, 2014, 69-year-old physician William Lewis Corporon drove his 14-year-old grandson to the Jewish Community Center of Greater Kansas City in Overland Park for the boy’s audition in a local singing contest. As they pulled into the rear parking lot, a gunman opened fire. Dr. Corporon was struck by a shotgun blast to the head and died at the scene; his grandson, Reat Griffin Underwood, was also shot and later died at a hospital. Both victims were Christian.

The attacker then drove to Village Shalom, a nearby Jewish retirement community, and shot a third person, 53-year-old Terri LaManno, who was visiting her mother. Witnesses said the gunman fired at several other people and missed; he was arrested by police officers at 2:45 p.m. near an elementary school after fleeing the scene. Reports state the attacker expressed antisemitic sentiments during the arrest and had a history of white supremacist activity and intent to target Jewish people, though none of the three people killed were Jewish.

Does anyone have information about William Corporon’s final movements that afternoon or about witnesses who saw the shooting in the parking lot?
