A whistle blowing worker testifying in the murder trial of a Philadelphia abortion provider said Thursday that she saw more than 14 babies born alive at the clinic.

Prosecutors chose 28-year-old Kareema Cross as their final witness before resting their case against Dr. Kermit Gosnell. Cross said she saw more than 10 babies breathe, with their chests moving up and down.

"I thought they were breathing," Cross testified. "He would say they're not really breathing."

Cross also described seeing three babies move, one after being born in a toilet, and heard a fourth give a "soft whine." Gosnell explained the movements as a last reflex amid the death process, she said.

Under defense questioning, Cross said she saw a baby move after its neck was snipped, and after it was given a drug meant to stop its heart.

Gosnell, 72, is charged with killing seven babies allegedly born alive, and with causing the 2009 overdose death of a 41-year-old refugee. Defense attorney Jack McMahon denies that there were any live births at the Women's Medical Society and blames the patient's death on preexisting medical conditions.
