Angela Early, a nurse at an assisted living home, is revealed to be the killer. A suspect in custody states that the victim found underneath the bridge was her son and approached her that night. The team learns Early was raped as a teenager and her parents forced her to keep the baby. Catherine asks Judge Burgess for help, and he points her to the nursing home. Early commits suicide to prevent being taken into custody.

Thomas's suggestion to Catherine about her mother deeply disturbs her. Meanwhile, the team investigates a possible domestic homicide where a mother and her children are killed. They later find the father dead from a gunshot wound, but his time of death occurred before his family's. Thomas suspects the killer hid in the house's crawlspace, and his re-enactment affects his own family, as the killer targets another one.
