Darius D. Marshall, 19, of Dolton, surrendered to authorities on Monday. He is charged with murder and attempted armed robbery, Dolton Police Chief John Franklin said. He is expected to appear in a Markham courtroom Thursday morning, the Sun-Times is reporting.
Marshall's attorney, Stuart Goldberg, has told the Chicago Sun-Times his client will plead not guilty. He turned himself in after his brothers, 16-year-old Anthony Lee and 21-year-old Diante Coakley, were charged over the weekend with Casara's murder.
Eva Casara, 17, was shot in the back of the head while prosecutors said she was participating in a botched Christmas Day robbery. She was 26 weeks pregnant with Lee's baby. Doctors delivered her infant, Lailani Paris Casara, before Eva Casara died on Dec. 26.
Prosecutors have said Casara plotted with Lee, Coakley and an unnamed brother to rob someone in Dolton on Christmas Day.
They said she set out with the brothers when they left their grandmother's house to commit the robbery at 152nd and Dorchester, where Casara made arrangements to meet their intended victim.
Once there, prosecutors said Casara got into a car with the intended robbery victim, his passenger, and Coakley. But the robbery victim eventually told Coakley to get out, and he did.
As Coakley tried to open the driver's side door, prosecutors said, the intended robbery victim drove off. Prosecutors said Coakley began shooting at the car even though Casara was in the back seat.
They said one other person fired shots, but it wasn't clear who the second triggerman was. It's thought that Coakley fired the fatal shot.
The robbery victim realized Casara was still in the car only when he and his passenger heard gurgling sounds from the back seat.
