Greg Zanis delivered 34 small wooden crosses to an empty lot in the city's Englewood neighborhood on the South Side over the weekend.
Each cross bears the name of a person killed so far in 2017. Local pastors joined for a brief vigil to pray for those victims and their families.
At least three more people were fatally shot in Chicago on Monday.
Last month, Zanis made more than 700 crosses for 2016 victims.
