25 Alive

At the Hall of Justice, Brady informs Lindsay that FBI Special Agent James Walsh is arriving to join the “I said. You dead” investigation. When Walsh arrives, Lindsay briefs him on the case, including her theory that the victims were targeted after gaining wealth.

Lindsay recounts discovering Jacobi’s body and shows Walsh the matchbook with the killer’s message. Walsh recognizes the block lettering, revealing that he worked the Sadie Witt murder case in Nevada, in which an almost identical note was found. He tells Lindsay he has a lead but requires her complete confidentiality.

To build trust, Walsh mentions that he knows and has worked with Lindsay’s husband, Joe. He reveals that his theory implicates a fellow FBI agent, whom he saw in Verne, Nevada, during the Witt investigation. He also connects the case to two earlier murders: a man in North Carolina and the agent’s own ex-wife.
