Antonio Williams was 19 when he was shot and killed on November 22, 2015.

Family and friends remembered Williams as loving and protective. He was known by several nicknames, including Tonio and 17 glizzy, and was described as outgoing and caring. His death was one of many young lives lost to gun violence in Chicago that year.

If anyone knew Antonio’s routines, friends, or who he was with that night, please come forward with information.
