4 Dead Including Police Officer After Shooting At Chicago Mercy Hospital

Updated at 9:07 p.m. ET

The Chicago Police Department says a police officer has died after he was shot at Mercy Hospital & Medical Center on Chicago's Near South Side, one of four killed in a domestic-related shooting.

Police spokesman Anthony Guglielmi identified the officer as Samuel Jimenez; the identities of the others killed in the shooting have not been released officially.

Witnesses described the shooting to The Associated Press:

"A witness named James Gray told reporters that it looked as if the attacker 'was turning and shooting people at random.'

"The shooting apparently began as the suspect was walking with a woman near a parking lot. He turned and repeatedly shot the woman in the chest. He then entered the hospital and continued firing, Gray said.

"The two had been talking to each other. Gray said it didn't seem like a heated exchange.

" 'Then once she fell to the ground, he stood over her and shot her three more times,' he said."

Other witnesses told the news service that the shooter then entered the hospital and continued firing for up to 15 minutes. A police spokesman told the station that the shooter was among the dead.
