On Sunday morning, May 31, 2009, George Richard Tiller, 67, was serving as an usher at Reformation Lutheran Church in Wichita, Kansas, when a gunman approached him in the lobby, placed a gun to his head and shot him at point-blank range. Tiller, who often wore body armor because of past threats, was struck in the head and died. Two people who tried to intervene were threatened by the assailant, who then fled in a powder-blue Ford Taurus.

Witnesses described the getaway car and an alert was issued. About three hours later, roughly 170 miles away in suburban Kansas City, authorities located the vehicle and arrested 51-year-old Scott Philip Roeder of Merriam, Kansas. A post-it note found on the dashboard linked Roeder to an anti-abortion activist; Roeder later admitted to killing Tiller and said the motive related to preventing abortions. Roeder was charged with first-degree murder and two counts of aggravated assault, and a jury later found him guilty.

Did anyone in the Wichita area see the powder-blue Ford Taurus that morning or notice anything suspicious at the church before the shooting?
