Two men were shot, one fatally, at the funeral of a reputed Chicago gang member.

The shooting happened outside St. Columbanus Catholic Church across the street from A.A. Rayner & Sons Funeral Home in the 300 block of East 71st Street, officials said.

Sherman Miller, 21, was dead on arrival at 1 p.m. at Stroger Hospital, a hospital spokeswoman said. Court records also identified him as William Miller.

The Gangster Disciples make up more than a quarter of Chicago’s 470 homicide victims. Nearly 60 percent of this year’s homicide victims were gang members.

Police were still investigating who was behind the church shooting, but investigators said the neighborhood had been plagued by conflict between the Gangster Disciples and the Black Disciples.

Prior to the shooting, police Superintendent Garry McCarthy had been discussing the department’s crime-fighting strategies in lowering the city’s violence rate earlier this year, when the number of homicides soared.

Rev. Corey Brooks, who officiated the service for 32-year-James Holman — no relation to the author of this article — said a church would have been off-limits to gang members at one time.
