Police are investigating a deadly shooting involving a police officer at Highland Park hospital.
Police were called to the hospital early Monday morning for a report of an aggressive patient.
When they arrived, officers say Christopher Anderson, 27, had a gun and refused to drop the weapon.
Officers shot Anderson and he died.
Police say he was brought to the hospital earlier in the night after a car accident.
Police say they didn't check Anderson for a gun after the accident because he wasn't accused of any wrongdoing.
No one else was wounded in the shooting and Highland Park hospital remained open Monday.
Anderson' relatives say they can't believe he would become aggressive, especially with his nine-year-old daughter in a hospital room next door.
