FBG Duck, whose real name was Carlton Weekly, is identified in the document as a member of the STL/EBT, or Tookaville, faction of the Gangster Disciples, which it said had feuded with O Block, a faction of the Black Disciples.
Weekly was killed at 4:26 p.m. on Aug. 4, 2020, according to the affidavit. Sixteen minutes earlier on Oak Street, it said, Weekly got out of a car driven by his girlfriend and stood in a line outside. Weekly’s mother has said he was shopping for a present for his son.
Around the same time, surveillance footage showed Liggins, Smart and others running down a stairwell at Parkway Gardens at 63rd and Martin Luther King Drive, according to the affidavit. It said Smart and another person got into a Ford Fusion owned by Offerd. The FBI believed Liggins got into a Chrysler 300 with two others.
From there, investigators were able to trace the vehicles’ path from Parkway Gardens to the scene of the murder, using video surveillance and police POD cameras.
