On August 20, 1995, a pipe bomb exploded outside the home of Shirley Phelps-Roper, the daughter of Fred Phelps. The blast damaged an SUV, a fence, and part of the house, but no one was injured. In 1996, two men were arrested for the bombing, and both admitted to causing the blast. They had believed Phelps-Roper's house was that of the pastor, and wanted to retaliate against Westboro's anti-gay protests at Washburn University. One of the bombers was fined $1,751 and was sentenced to 16 days in prison plus 100 hours of community service.
