The group therapist refused to disclose to the detectives who might have had reason to harm the victim, claiming that divulging that information would be violating doctor/patient privilege. However if a doctor (the same applies for a lawyer) has reason to believe that their patient is planning on harming them-self, or someone else; or learns from their patient that someone is harming them, or is going to in the future, the doctor actually is not only allowed to violate doctor/patient privilege, but is required by law to report their suspicions to the police.
