The news of her death comes on the same night that 911 calls from that fateful January evening were released by authorities.
The calls captured the moment that Nightengale opened fire in a CVS location near the border of Chicago and Evanston. After leaving that store, he then moved across the street, where he shot 61-year-old Marta Torres. She later died from her injuries.
Nightengale then fled from the restaurant and was running toward a Dollar General when he was shot by Evanston police officers.
He was pronounced dead at an area hospital a short time later.
That day, Smith was riding in a vehicle with her mother about 4 p.m. in the 10300 block of South Halsted Street when she was shot in the head, officials said. Nightengale is believed to be responsible for the shooting.
