| The suspect, who has not been apprehended, pulled a gun 
				during an argument with a 41-year-old woman on the mezzanine 
				level of a south side Chicago train station around 10:45 p.m. 
				local time, Chicago Police news affairs officer Amina Greer 
				said.
 The woman and a 25-year-old man were hit, and both were rushed 
				to a local hospital in critical condition. A 24-year-old man was 
				also injured after being hit in the face by glass fragments, 
				Greer said.
 
 Police are investigating the shooting. It is unclear if the 
				suspect or victims knew each other.
 
 Greer said there were no service interruptions for the Chicago 
				Transit Authority.
