Martin Dean, 57, was arrested Tuesday in the death of Allen Jackson, 38, on Jan. 1.
Police say Dean and Jackson were fighting in the 5000 block of South State Street when Dean hit Jackson in the head with a blunt object.
Jackson was taken to the University of Chicago Medical Center, where he was pronounced dead.
Dean was due in bond court Thursday.
The killing was the city’s first of the year, following a violent 2021 that saw more than 800 murders.
