"I was sitting on this table, and he had this sucking machine," Williams said. "He sucked it [the fetus] out. It hurt so bad."
The abortion should never have taken place.
Stacy Kriedeman, a spokeswoman for the Pennsylvania Department of Health, said that since 1974, the state Abortion Control Act has required abortion doctors to have "informed consent of one parent" before they can perform an abortion on a minor.
"Failure to meet the parental consent requirement is deemed unprofessional conduct and results in suspension of medical license," Kriedeman noted.
Williams said her parents didn't know she had sneaked to Gosnell's clinic.
After the procedure, Williams said, she felt dazed. She began sobbing when she discovered the nearby room that was packed with fetus remains.
"He told me the morgue comes and gets the babies and burns them," Williams said, her voice growing quiet.
"I asked him, 'How do you do this? Doesn't it bother you?' " she added. "He said he tried not to think about it."
A week later, Williams said, she developed an infection and returned to Gosnell's clinic for medication. He grew quiet when she asked him how the infection occurred.
"It was only after that I started hearing rumors about people getting sick in there, that he didn't even clean the instruments he used."
