It happened when he was making his regular visit to "Lets Get Poppin" popcorn shop in Morgan Park on the afternoon of Dec. 3. A growing memorial now marks the spot where he was killed.
The shop plans to hold a fundraiser Thursday afternoon. Customers are asked to buy a bag of Williams' favorite popcorn for $10 a bag, in which a portion of the proceeds will go to his family.
Police released video of the carjacking in hopes of identifying the suspects. There is also a reward of at least $34,000 being offered for information leading to an arrest in the case.

Chicago police are now battling a dramatic increase in carjackings, with more than 1,200 reported so far this year. There were 501 reported at this time in 2019.
Detectives hope this video will help take some of those offenders off the streets and bring some peace to Williams' family.
