During the six-week trial, which has drawn a national spotlight, prosecutors called numerous witnesses to testify that Gosnell routinely performed abortions beyond Pennsylvania's 24-week limit, often injured women under his care and repeatedly "snipped" the spinal cords of babies born alive after women in his clinic went into labor.
They have painted his clinic as a "house of horrors" where untrained and unsupervised staff members pumped patients full of dangerous medications and where Gosnell showed little regard for the low-income women who came through his doors.
Many of the witnesses were past employees who have pleaded guilty to various crimes and agreed to testify against their former boss.
McMahon has maintained that no live births took place at the clinic because Gosnell terminated the pregnancies in utero. He also argued that Mongar, who had recently immigrated to the United States, died from unforeseen complications rather than from an ill-advised dosage of drugs. Gosnell did not testify during his trial, and the defense called no witnesses.
Beyond the murder charges, Gosnell faces hundreds of other criminal counts, including numerous allegations of performing third-trimester abortions, racketeering and failing to counsel patients in advance of performing abortions. Gosnell could face the death penalty if convicted on the charges of first-degree murder in the deaths of the four babies.
