The father of 9-year-old murder victim TyShawn Lee, was charged with attempted murder of 3 people.
Pierre Stokes, 25, was charged with three counts of aggravated battery for shooting a woman and two men in Chicago Tuesday.
All 3 victims, including the girlfriend of one of TyShawn's alleged killers, survived their injuries.
2 gang members, Corey Morgan and Dwright Boone-Doty, have been charged with TyShawn's murder.
Stokes allegedly shot Morgan's 29-year-old girlfriend and the two men, 30 and 31, on the same day that Cook County prosecutors revealed Stokes was cooperating in the investigation into his son's death.
According to the Chicago Tribune, Boone-Doty, Morgan and a 3rd man spotted TyShawn playing in a Dawes Park lot on the afternoon of Nov. 2, and offered to take him to a store and buy him anything he wanted.
Boone-Doty later told investigators his plan was to torture TyShawn by cutting off his fingers and ears.
The 3 thugs followed TyShawn to an alley near his grandmother's house, and Boone-Doty allegedly shot him multiple times.
TyShawn's murder was reportedly a revenge killing for the gang-related murder of Morgan's brother, Tracey Morgan, in October.
Boone-Doty told police he conducted surveillance on Tyshawn's grandmother with plans to kill her in order to draw out rival gang members, including TyShawn's father, Pierre Stokes.
Stokes is reportedly a member of the Killa Ward faction of the Gangster Disciples.
Corey Morgan was overheard saying he was targeting "grandmas, mamas, kids and all" to avenge his brother's death.
Authorities have issued an arrest warrant for Kevin Edwards, the third suspect in Tyshawn's killing. He is believed to be hiding out in Iowa.
