An anti-abortion leader says his group may try to buy the now-closed Wichita abortion clinic owned by a doctor who was shot to death last month.

The leader, Troy Newman, the president of Operation Rescue, said on Wednesday that his group, which had long fought to close the clinic, was considering trying to buy the squat, beige building to perhaps turn it into a memorial museum, “a tribute to the babies.”

For decades, the clinic, Women’s Health Care Services, had been operated by Dr. George R. Tiller, who was killed on May 31 as he served as an usher at his Wichita church. It was one of a few clinics in the country where women could receive abortions late in their pregnancies.

On Tuesday, members of Dr. Tiller’s family announced that they were permanently closing the clinic, setting off a flurry of concerns from abortion rights groups that women would now find it more difficult to find facilities willing to provide abortions in circumstances when catastrophic health issues were discovered late in pregnancy.
