Shortly before 10 a.m. on Sunday, December 11, as Kennedy was preparing to leave for Mass at St. Edward Church in Palm Beach, Pavlick waited in his dynamite-laden car hoping to detonate his 1950 Buick to cause a fatal explosion. However, Pavlick changed his mind after seeing Kennedy with his wife, Jacqueline, and the couple's two small children. Pavlick said, "I did not want to harm her or the children." While waiting for another opportunity over the next few days, Pavlick visited the church to learn its interior, but the Secret Service had informed local Palm Beach police to look out for Pavlick's automobile.
