PHILADELPHIA (AP) — Prosecutors preparing to try a Philadelphia abortion doctor charged with killing a patient and seven babies want the jury to hear evidence he allegedly ran a pill mill and let unskilled workers practice medicine.

Dr. Kermit Gosnell's lawyer hopes to keep any such evidence out of his March murder trial.

Gosnell faces a second trial on federal drug charges, which allege he distributed painkillers like candy at his West Philadelphia clinic.

Prosecutors say in a recent motion that breaking the law was "standard operating procedure." They say the deaths were no accident but the result of dangerous medical practices that went on for decades.

At a hearing Monday, a judge set pretrial arguments for Oct. 29. Gosnell is charged with killing babies born alive. He's pleaded not guilty.
