This episode covers part two of the Keddie Cabin murders, focusing on the 2013 re‑investigation led by retired deputy-turned-PI Mike Gamberg and the chaotic, mishandled evidence left from the original 1981 inquiry. Unopened evidence bags, a missing case history log, and degraded DNA samples reveal major investigative failures.

New leads discussed include a 2016 discovery of a hammer matching a suspect's description, a Butte County dispatch recording about Tina Sharp's remains, a DNA match to a living person of interest, and a handwritten letter that reads like a possible confession.
