Something worth noting here: LE noted numerous times how emotionless Shelie was during questioning and other proceedings. They were, however, astounded to find her on the streets of Quincy, laughing and giggling and living it up with her friends.
Of actual note: Sheila was staying in EQ. 200 yards from co-conspirators, the Meeks. The friends she was seen with had to include them, particularly LaRonda.
LaRonda told Gam she had boxes of Keddie-related stuff to give him "once Mama dies". Dead all these years, as expected, is LaRonda's promise.
