1 stolen gun linked to 27 shootings in Chicago. On January 1, 2016, a burglar stole several firearms, including a Glock 17 9mm, from a gun store in northern Wisconsin. In a deep-dive investigation, The Chicago Tribune tracked the firearm’s subsequent journey to the black market, its use in more than two dozen crimes, and the tragedies shooters left in their wake. The first shooting linked to the gun occurred on February 5, 2016. Twenty-six more shootings and nearly 20 months later, Chicago Police recovered the gun on July 26, 2017. All told, 24 people were shot with the Glock, two of them fatally. Police charged people only in the homicide cases connected to the gun. The firearm’s last possessor was Cory Stone, a 29-year-old gun violence survivor who served more than two years in prison after being charged with illegal gun possession. He was never connected to any of the shootings. “My intention was to protect my family,” said Stone, who bought it on the street.
