He tries to enter the apartment of another woman, only to find that her husband is home. DeSalvo is apprehended by a passing police patrol. Found incompetent to stand trial for attempted breaking and entering, he is committed to a hospital for psychiatric observation. By chance, Bottomly and Detective Phil DiNatale (George Kennedy) pass by DeSalvo in an elevator, where they had been visiting Dianne, who survived the earlier attack. Observing the wound on DeSalvo's hand (Dianne, who survived his attack, could remember biting him but not his appearance), the pair make him a suspect for the Boston Strangler murders.
