Authorities say Dr. Kermit Gosnell ran a "pill mill" by day and a rogue "abortion mill" by night.
His high-profile murder trial this spring came after federal drug agents raided his West Philadelphia clinic in 2010. They charged him with selling prescriptions for OxyContin and other painkillers to people who lined up at the front desk.
A state jury last month convicted the 72-year-old doctor of three counts of first-degree murder for killing babies after they were born alive.
Defense lawyer Jack McMahon has said Gosnell will plead guilty to the drug charges, given the outcome of the murder case.
