The man accused of murdering a prominent abortion provider Dr. George Tiller has testified at his trial that he did fatally shoot the doctor.
Scott Roeder testified Thursday that he killed Tiller in the foyer of Tiller's Wichita church on May 31. Tiller was one of only a few late-term abortion providers in the U.S.
The 51-year-old Roeder also said he believes abortion is murder.
Roeder took the stand just after District Judge Warren Wilbert barred Kansas' anti-abortion crusading former attorney general Phill Kline from testifying.
Roeder has pleaded not guilty to first-degree murder and aggravated assault in the case.
The defense wants to show that Roeder was relying on Kline's belief that Tiller was breaking the law _ a potential step toward a lesser manslaughter conviction.
