Jury selection for Kermit Gosnell's trial began Monday.
The Women's Medical Society was initially raided in February 2010 on suspicion Gosnell was illegally selling thousands of prescriptions for Oxycodone, anti-anxiety medication and codeine-based cough syrup from 2008 through January 2010.
The raid uncovered stored, dismembered fetuses -- some of which were said to have been viable -- and evidence of late-term abortions.
Gosnell is charged with third-degree murder in the death of a woman who died after untrained staff members allegedly administered too much anesthesia during an abortion, The Philadelphia Inquirer reported. He also faces first-degree murder charges in the deaths of seven infants.
Nine of Gosnell's employees -- including his wife, Pearl Gosnell -- also face charges.
Medical school graduate Eileen O'Neill was to go on trial Monday to face charges she worked at the clinic without a medical license, her attorney, James Berardinelli, said.
