The reporter who interviewed him, David Gambacorta, told CNN that Gosnell believed he was helping an under-served population in his West Philadelphia neighborhood.
When authorities searched Gosnell's office, they found bags and bottles holding aborted fetuses scattered throughout the building.
Jars containing the severed feet of babies lined a shelf. Furniture and equipment was blood-stained, dusty and broken.
"My grasp of the English language doesn't really allow me to fully describe how horrific this clinic was -- rotting bodies, fetal remains, the smell of urine throughout, blood-stained," Williams said.
Williams described one of the alleged infant deaths.
"The baby had been born and was on a cold steel table and murdered by using -- there's no medical basis for snipping or taking scissors and putting them into the neck and cutting, severing the spinal cord. It's just homicide. It's just murder," Williams told CNN.
According to Philly.Com, a joint website of the Philadelphia Daily News and the Philadelphia Inquirer, Gosnell was back in court last Thursday, to mull a possible plea bargain.
It's unclear what the outcome of the meeting was, because of a gag order imposed on attorneys and other people involved in the case.
