Roderick Gailes, 26, of Springfield was arrested Tuesday, October 10.
Devante Taylor, 24, of Belleville was arrested last week.
Both are charged with two counts of first-degree murder, one count of attempted armed robbery and one count of aggravated discharge of a firearm.
They are being housed in the Sangamon County Jail and will be in court on Thursday.
Officials say Taylor is allegedly the shooter in this case.
"This is one step closer to bringing justice to the family of Alaysia Bennett and bringing those responsible to justice in this case," said John Milhiser, Sangamon County State’s Attorney.
The case is still under investigation at this time.
The state's attorney said more arrests could be made.
