The main events of the NCIS episode Parental Guidance Suggested

The 10-year-old Rachel Barnes found her mother, Lieutenant Commander Anne Barnes, deceased upon coming back from a sleepover. Naval Criminal Investigative Service arrived to investigate.
Anne worked in forensic criminal therapy as a trained professional. Rachel found comfort inside her blanket fort, which she considered her refuge. According to Gibbs's Special Agent interview, Rachel thought that someone was trying to harm her father.
Lieutenant Commander Ryan Barnes, a Marine, was linked to the operation that killed terrorist Benham Parsa. Homeland Security confirmed he was on a jihadist target list, leading NCIS to suspect his murder was an act of terrorism.
Investigators reviewed Anne's professional activities. She had been visiting a convicted serial killer as part of her work, gathering insight into sociopathic behavior.
She provided professional therapy services to people at high risk who had criminal records. This led NCIS to explore whether the murder was committed by someone with a personal grievance tied to her profession.
The staff checked digital database entries and conducted interviews to locate one of Anne's former clients who formed an unhealthy emotional bond with her. He was supposed to have monitoring, but instead, he carried past criminal conduct.
Naval Criminal Investigative Service teams found and arrested the targeted person following their online monitoring. Upon investigation, he accepted responsibility for killing Anne, claiming Anne had betrayed him by recommending involuntary commitment, which made him lose control.
The social services agency sends Rachel Barnes to live with members of her extended family. Official search results determine terrorism is not at play and show clear evidence of obsessive behavior behind the crime. The episode ended with the Naval Criminal Investigative Service team concluding the case.
