IMO gang bangers and drug dealers normally have criminal records and don't hold down jobs at Target for eight years. CM has no record whatsoever. I believe CM's sister was in court taking notes, along with another older female. Could have been his mother or other relative. If CM's a wanna be hit man, why take Sal's keys? Why not just walk up, shoot and run? If Gianni was the target, why walk inside the mall presumably after Gianni was dead and talk to Ilona and follow her out? (One possible answer, the man seen on surveillance video was not the killer, but just a random guy).
