Roeder told jurors that he bought a .22-caliber handgun on May 18, went target shooting with it on May 30, and used it to shoot Tiller in the forehead while Tiller was serving as an usher in his church.Roeder will be sentenced March 9. Prosecutors are seeking 50 years with no possibility of parole.
Roeder also revealed that he had taken a loaded gun to Tiller's church on three previous occasions -- in August 2008, the Sunday before the shooting and the night before the shooting -- but Tiller was not at those services.
Roeder testified that over the years, he'd considered other ways to stop Tiller from performing abortions, including cutting Tiller's hands off with a sword, ramming Tiller's car with his own, and taking a sniper shot at Tiller outside his clinic. But he said he ended up choosing to kill Tiller in his church because "it was the only window of opportunity that I saw where he could be stopped."
