A Kansas grand jury investigating notorious abortionist George Tiller adjourned its six-month investigation Wednesday without an indictment. Tiller is accused of performing illegal late-term abortions at his Wichita clinic.

The panel of 15 said it failed to find enough evidence to indict Tiller. The jurors also suggested that state abortion laws are unclear.

Mary Kay Culp, executive director of Kansans for Life, said she believes the grand jury was led astray by the prosecutor.

“The failure of the grand jury to deliver indictments today is a tragic injustice for all law-abiding Kansans,” she said. “This grand jury would have surely indicted George Tiller had they not been misinformed. The problem isn't the current law. The problem is the so-called enforcers of that law that have failed to do their job.”

Operation Rescue President Troy Newman has pledged to continue seeking justice.

“We are extremely disappointed that this grand jury did not indict Tiller,” he said. "We will not stop seeking justice for the innocent victims of Tiller's late-term barbaric practice, and will continue to exercise every legal avenue to stop the shedding of innocent blood and bring Tiller to justice."

Tiller still faces 19 misdemeanor charges filed by the Kansas attorney general’s office that allege he violated a section of the state abortion law that requires a second and independent doctor's consent before a late-term abortion. That trial is scheduled for July 28.
