Police are retracing the gun used to fatally shoot Martin as she walked home from school on Monday. Officials say a 14-year-old girl pulled the trigger after she and Martin got into a Facebook fight over a boy. She is charged as a juvenile, and has not been named.
Officials say Evans illegally bought the gun from Robert James, 34, in November. James, who legally owned the gun, reported it stolen on April 15, 2014, and is now charged with unlawful delivery of a weapon and filing a false police report.
Evans is charged with a misdemeanor of owning a firearm without a valid FOID card and also faces charges on an outstanding warrant.
The gun was then given to Donnell Flora, 25, police said. Flora allegedly provided the murder weapon to his 14-year-old niece, who is accused of pulling the trigger. A 17-year-old who allegedly tried to flee with the gun after the shooting is also charged.
A sixth person, the alleged shooter's aunt, is also charged. Vandetta Redwood, 32, faces charges of mob action and obstruction of justice.
Chicago police say cell phone video of the shooting shows Redwood at the murder scene.
