Active Shooter Reported at Mercy Hospital in Chicago

A victim, as well as the shooter, is dead after a gunman shot up Chicago's Mercy Hospital around 3:20p.m. local time on Monday, while four others have been wounded, including a police officer. Two women who were shot are in "extremely critical condition."

The Chicago Police Department warned of a "heavy police response" coming to the area following "reports of shots fired." At least "one possible offender" had been shot, police said. Less than six people were wounded in total, a law enforcement source told the Chicago Tribune. However, that number has been updated to six if the gunman is included.
