The Episode When They Found Al’s DNA At a Site
That was Season 5. Al was under investigation for covering up for Voight when Voight killed Bingham for killing his son. Al’s DNA was at the scene. Al was asking Voights help with the lawyer fee and Voight said all the money went towards a trust fund for his grandson.
Mean to tell me that Voight couldn’t try to help with the lawyer fee when Al took the fall and was even killed in prison.
