Later, Patrick identifies and arrests the cop killer Todd Johnson. However, Todd is killed in his cell. A police officer from another department, J.J. LaRoche, forms a list of suspects. Patrick wants to find out who is on this list of suspects. For this, he hires Donald Culpepper. However, he is caught. Donald demands that Patrick take him out of the cell according to the law. Patrick asks Teresa Lisbon for help. She beats Donald. After that, he is released. Teresa is punished. Then, someone steals a mysterious container from LaRoche, which (most likely) contains the tongue of his mother's rapist. LaRoche is blackmailed with this. The culprit turns out to be Brenda Shettrick. She is arrested. It was Donald who sold her the information about that container. It later turns out that he got married and moved to Venezuela.
