Birmingham Police Sgt. Johnny Williams says the officer and employees suffered injuries that are not considered life-threatening.
The gunman reportedly opened fire as the victims were coming off the elevator. A second police officer came around the corner and shot and killed the gunman, MyFoxAL.com reports.
Williams says police were called because a man with a gun was walking through St. Vincent's Hospital on Saturday morning. The hospital issued a "Code Silver" using the intercom which alerts the staff that there is harm or threat with a weapon.
Police are hoping surveillance video taken on the floor will help them determine what happened. A hospital spokeswoman told MyFoxAL.com that employees go through security training to deal with incidents like this.
Detectives are still working to determine why the armed man was in the hospital.
