Scott Roeder, 51, of Kansas City, Mo., is charged with one count of first-degree murder in Dr. George Tiller's death and two counts of aggravated assault for allegedly threatening two ushers who tried to stop him during the May 31 melee in the foyer of the doctor's Wichita church. Roeder has pleaded not guilty and his trial begins Monday.
Roeder faces life imprisonment if convicted of first-degree murder. A voluntary manslaughter conviction could bring a prison term closer to five years, depending on prior criminal record.
Voluntary manslaughter is defined in Kansas law as "an unreasonable but honest belief that circumstances existed that justified deadly force."
Sedgwick County District Judge Warren Wilbert ruled that defense attorneys can present evidence to support such a conviction. He said he will consider everything Roeder's lawyers present at trial before deciding whether to tell jurors if they can consider a conviction on a lesser offense.
The judge warned defense attorneys they faced "a substantial uphill battle" in showing Roeder had a sincere belief that the use of deadly force was necessary in the defense of others.
"This will not become a trial on the bigger issue of abortion. It will be limited to Mr. Roeder's beliefs," Wilbert said.
Roeder has confessed to reporters to shooting Tiller, saying it was necessary to save "unborn children." He filed a motion made public Friday in which he admitted to the court that he killed Tiller, arguing his trial would be a "charade" if he could not present to jurors his only defense. He asked the judge to reconsider his decision last month prohibiting a so-called necessity defense.
Such a defense would allow his attorneys to argue for acquittal on the grounds that the shooting was justified.
Wilbert again denied the request, telling Roeder at Friday's hearing that the argument "I had to shoot and kill Dr. Tiller to save unborn babies" from abortion doesn't meet the necessity defense because abortions are legal and there has never been a finding that Tiller was performing illegal abortions. Wilbert said the argument also fails by its very definition because one life is not worth more than another.
