A police officer, a doctor and a pharmaceutical assistant were killed after a Monday afternoon shooting at Chicago's Mercy Hospital, Mayor Rahm Emanuel said.
The gunman, who was in a relationship with the one of the victims, also died, Chicago Police Superintendent Eddie T. Johnson said. It's not clear if he died from police gunfire or a self-inflicted gunshot wound, Johnson added.
Chicago Police identified the deceased officer as Samuel Jimenez, a father of three. He joined the force in February 2017 and recently completed probationary training, becoming a full-fledged officer, Johnson said. A procession was held for him Monday night.
