Blank Generation (S02E11)

At the urging of the deceased's sister, Rush and Valens reopen the 1978 suicide of Matthew Adams (Bug Hall), a cult member who died of cyanide poisoning. Initially, the detectives investigate the man hired to deprogram Matthew. After the manner of the death of Matthew's mother is revealed, his father becomes suspicious. And the discovery of a love triangle turns the team's attention to the imprisoned leader of the cult. But by the time the investigators uncover the truth, the killer tries to strike again, and this time Rush is his target. Meanwhile, someone very close to Valens is found dead...an apparent suicide.
