Two employees of a Philadelphia abortion clinic where live, viable babies were allegedly killed and a patient died after being given on overdose of painkillers pleaded guilty on Thursday to murder.

Guilty pleas to third-degree murder were entered by Adrienne Moton, 34, and Sherry West, 52, who both worked for Dr. Kermit Gosnell at what prosecutors have described as a decrepit and unsanitary clinic known as Women's Medical Society in West Philadelphia.
