A Kansas jury deliberated just 40 minutes before convicting an anti-abortion activist of first-degree murder in the fatal shooting of an abortion provider.

The jury found Scott Roeder, 51, guilty of gunning down Dr. George Tiller, who operated a clinic in Wichita where late-term abortions were performed. Roeder, 51, faces life in prison when he is sentenced on March 9.

Tiller's family said the jury reached a "just" verdict.

"At this time we hope that George can be remembered for his legacy of service to women, the help he provided for those who needed it and the love and happiness he provided us as a husband, father and grandfather," the family said in a written statement.

A day earlier, Roeder told jurors he had shot Tiller in the foyer of Reformation Lutheran Church as Sunday services began. Testifying as his only defense witness, he said he believed he had to kill Tiller to save lives. He said he had no regrets.

"There was nothing being done, and the legal process had been exhausted, and these babies were dying every day," Roeder said. "I felt that if someone did not do something, he was going to continue."

This statute is much longer and determines when an abortion is valid:

(4) the probable gestational age of the fetus at the time the abortion is to be performed and that Kansas law requires the following: "No person shall perform or induce an abortion when the fetus is viable unless such person is a physician and has a documented referral from another physician not financially associated with the physician performing or inducing the abortion and both physicians determine that: (1) The abortion is necessary to preserve the life of the pregnant woman; or (2) the fetus is affected by a severe or life-threatening deformity or abnormality."[*] If the child is born alive, the attending physician has the legal obligation to take all reasonable steps necessary to maintain the life and health of the child;

Per Kansas law Tiller was not performing abortions of viable fetuses unless the mother's health was in danger.
