Police released the 911 calls made by witnesses of the Johns Hopkins Hospital shooting.
A frightened patient at Johns Hopkins Hospital told 911 operators that her parents were trying to keep the door to her room shut tight after they heard a shot outside.
The recordings of 911 calls released Friday detail the tense moments after a man opened fire on a surgeon who was updating him on his mother's condition. The doctor, identified as Dr. David Cohen, was wounded and is expected to survive.
Another caller told an operator she was standing near the doctor by a nursing station when the doctor went down yelling "Help! Help! Help!" She said the shooter ran back into a room and people began screaming at others to run.
Police said the distraught shooter, Paul Pardus, who was upset about the prognosis for his 84-year-old mother, then killed her and himself.
