One police officer killed, another critical in Chicago hospital shooting

A police officer died and another was critically injured after a man in police custody and receiving treatment at a Chicago hospital opened fire on them Saturday, according to officials.

"Officers transported an individual over to the Swedish hospital for an observation, at which time two of our officers were shot," Chicago police Superintendent Larry Snelling said at a news conference in the afternoon. "One was shot critically. It (the death) was pronounced. The second officer right now is fighting for his life in the hospital behind us."

The officer remained in critical condition Saturday evening, authorities said in a statement.

The suspect, who was not publicly identified, fled the Endeavor Health Swedish Hospital after the shooting at around 10:50 a.m. He was later detained and a gun was recovered, police said.
