CHICAGO (CBS) — A 21-year-old man has been charged in the death of a toddler who was struck and killed by a vehicle fleeing the scene of a fatal shooting this weekend.

The child’s mother and other family members attended the bond hearing for Watkins today, but had to leave the courtroom after she screamed “you killed him.”

A memorial marks the spot where 13-month-old Dillan Harris was struck and killed Saturday afternoon, while he was waiting at a bus stop, strapped into a stroller, near 63rd and Ellis.

Shortly after the crash, Watkins and another man were taken into custody in that area. Police said Watkins and the other man were suspected in the fatal shooting of 22-year-old Marvin Carr, about three miles away from where Dillan was struck.

Carr, a rapper known as Capo, is also a known associate of rapper Chief Keef, and is a member of his Glo Gang. He had recently returned from a recording session in Los Angeles, when he was shot in an apparent drive-by in the 7700 block of South Kingston on Saturday.

Police said Watkins and the other man were fleeing the scene of that shooting when they struck Dillan as he and his mother were waiting for a bus. Watkins allegedly was driving the car that struck and killed Dillan.

So far Watkins has not been charged in connection with the shooting of Carr, but he and the other man were still being questioned in connection with that killing as of Monday morning.

Keef is now living on the West Coast, but planned to hold a benefit concert to raise money for Dillan’s family. He will appear via hologram, rather than in person, due to outstanding arrest warrants that members of his legal team say limit his movement.

“I would much rather see him decide that he’s not going to do anymore music glorifying violence and guns in the city or in the country,” said Father Michael Pfleger.
