Glo gang affiliate Capo was gunned down Saturday in Chicago.

But what took the murder from another all-too-familiar case of "Chiraq" violence to an almost unspeakable tragedy was that the alleged gunmen ran over and killed a one-year old baby in a stroller as they fled the scene.

According to Billboard, Glo Gang leader Chief Keef was "just so heartbroken and appalled" by the two deaths that he has decided to hold a July 17 benefit concert for 1-year-old Dillan Harris.

But there's a twist. Keef currently resides in Los Angeles, and can't return to his hometown of Chicago because of outstanding warrants.

So he's going to perform the concert via a hologram broadcast from a Beverly Hills sound stage.

Admission to the show will be free, with donations requested for Harris's family.
