A gunman who shot and killed three people, including a police officer, at a hospital on the South Side of Chicago, had recently broken up with one of the victims, a doctor who he confronted to demand she give him back the engagement ring he bought her, police said Tuesday. A police spokesman said the gunman was dead, but it was not immediately clear if he took his own life or was killed by police. According the Associated Press, the medical examiner says it has been notified of four deaths from the shooting that took place at Mercy Hospital on the city's South Side. Anthony Guglielmi, chief communications officer for the Chicago Police Department, said on Twitter that the officer was critically wounded in the incident at Mercy Hospital and Medical Center about 26 blocks south of the Chicago Loop. James Gray told ABC 7 that he saw multiple people shot: “It looked like he was turning and shooting people at random.”

Mayor Rahm Emanuel was huddling with Chicago Police Superintendent Eddie Johnson at city’s public safety headquarters where officials were monitoring the events, according to the mayor’s spokesman, Adam Collins.
