Kara and Matt Black were in that situation four years ago. The couple first learned there was a problem with the pregnancy during an ultrasound at 20 weeks. It then took more time to get a proper diagnosis from specialists. Doctors told Kara and Matt the baby's heart was missing a chamber that fed oxygen to the lungs. Her heart wasn't pumping blood properly and was filtering contaminated blood back into her system.
Kara said she had the option of carrying to term at which point doctors would administer what they called "compassionate care," a process of giving the baby morphine until she passed away. Or they could opt for three open heart surgeries and hope the baby survived.
"They did say that with each open heart surgery you lose a third of your cognitive ability, and she would be severely retarded," Kara said. Doctors told the couple in the best case scenario the baby would live 3 to 5 years, on and off respirators.
"How do you recover from a lost three- to five-year-old as you watch them die slowly?" Kara asked.
Dr. Tiller performed Kara's abortion. The Blacks now have two other children.
"If people knew what he really was doing out there and dropped this fairytale that you get pregnant [and] you get a healthy baby. It doesn't happen like that," Kara Black said. "You know, sometimes your body does not miscarry, and you have to deal with cards that you're dealt."
One week after his death, Tiller's clinic remains closed. On the clinic's Web site, Tiller's family asks that people respect their privacy. They have also issued a statement saying they have no plans to reopen it anytime soon.
The same anti-abortion groups that have spoken out against Tiller's practices have also denounced his accused murderer's actions, saying two wrongs don't make a right. However, they maintain their stance that Tiller was wrong.
Tom McClusky, vice president of the Family Research Council, said that in the anti-abortion movement, any abortion is wrong.
"In the case of late-term abortion, these are children that have arms, have legs, feel pain," he added.
