Dr. Gosnell “induced labor, forced the live birth of viable babies in the sixth, seventh, eighth month of pregnancy and then killed those babies by cutting into the back of the neck with scissors and severing their spinal cord,” Mr. Williams said.

Mr. Williams said patients were subjected to squalid and barbaric conditions at Dr. Gosnell’s Women’s Medical Society.

Authorities went to investigate drug-related complaints at the clinic last year and stumbled on what Mr. Williams called a “house of horrors.”

“There were bags and bottles holding aborted fetuses were scattered throughout the building,” Mr. Williams said. “There were jars, lining shelves, with severed feet that he kept for no medical purpose.”
