Three people - a police officer and two employees - have been killed in a shooting at a Chicago hospital.
The incident started with an argument in a car park outside Chicago's Mercy Hospital at around 3:30pm local time on Monday.
The suspected gunman is said to have shot his former partner - a doctor at the hospital - in the car park.
After being surrounded by police, the suspect fled into the hospital.
Inside, he is said to have shot and killed a pharmaceutical assistant as she stepped out of a lift.
A police officer, who has been named as Samuel Jimenez, was also killed by the gunman inside the building.
Authorities said the suspected gunman also died inside the hospital - with police noting that it was not immediately clear whether it was a result of being shot by police or a self-inflicted gunshot wound.
Praising Officer Jimenez, Chicago Police said: "His heroic actions saved countless lives.
"He ran toward danger. He ran toward those shots. He ran into fire. Selflessly."”¬
