A man devastated by his mother's analysis shot her doctor Thursday at the world-renowned Johns Hopkins Hospital in Baltimore before supposedly killing her and taking his own life. Officials would not instantly elaborate on the diagnosis that sparked the shooting, but reports speculated that the suspect's mother may have been paralysed after spinal surgery.After initially identifying the 50-year-old gunman as Warren Davis, police later discovered this was an alias he gave to hospital staff and said he was actually Paul Warren Pardus of Arlington, Virginia. After a three-hour standoff in the mother's hospital room, police entered the room and found Pardus dead from a gunshot wound and his mother insensitive in the bed, apparently killed by her son. The doctor, who was shot once in the abdomen, was in surgery, but his wounds were not considered to be life-threatening.
