Harris denies any involvement and is confident that his wife can (and will) post the $5 million bail as she does not believe he had anything to do with the murders. The victims are held for two days before they are strangled to death. The victims are also alternately a white woman then a black woman. The latest possible victim is Missy Dewalt, who has been missing for a few hours. However, her dead body is found within the day, the time of death being when Harris was in custody. Based on a secret blog found deleted from Harris' computer and Missy's death, the BAU are certain that Harris is the murderer but has an accomplice. Harris daughter, Andrea, grows suspicious of his involvement in the murders and sees the signs provided to her by the BAU of her father's possible accomplice.

Episode 13: Bloodline
Original Air Date—21 January 2009
Ten year old Cate Hale is abducted from her rural Alabama home while her sleeping mother and stepfather are killed, their throats slashed. Although the BAU realize that time is of the essence since most abducted children do not survive past the first 24 hours, Cate is later released, physically unharmed. The BAU believe her release was due to the fact that she has epilepsy, which the unsub did not know of prior to her abduction. Cate recounts that her abductors were a family: a mother, father and son around her age. From Cate's stories of the abduction and later evidence found, the BAU piece together that the abduction and murders have a ritualistic nature to them. During the investigation, a second young girl in the area is abducted, her parents also killed in a similar manner. It isn't until Garcia does a search of past similar cases - abducted young girls with their parents killed - that the BAU begins to understand the full nature of this case and the rituals involved, in addition to who the mother abductor potentially could be.
