Crime Stories with Nancy Grace

Nancy Grace and her expert panel examine the murder trial of Lindsay Clancy, a former labor and delivery nurse accused of strangling her three young children: Cora, 5, Dawson, 3, and eight-month-old Callan. Clancy wrapped exercise bands around the children's necks in their home's basement before slitting her wrists and jumping from a second-story window. The team analyzes the prosecution's argument that Clancy meticulously planned the killings after searching ways to kill online and sending her husband out for takeout food and pharmacy prescriptions, contrasting it with defense claims that she suffered a severe psychotic break triggered by postpartum psychosis and a cocktail of psychiatric medications. Nancy breaks down what happened in court, reviewing testimony from a lifelong friend, distressing autopsy findings, emergency dispatch recordings, and the details of a jury walkthrough at the Duxbury crime scene.

Five people were arrested in the death of actor Mathew Perry. Federal Prosecutors alleged Perry first obtains ketamine from an unscrupulous doctor aiming to take advantage of the actor’s addiction issues. Dr. Salvador Plasencia teaches Perry’s live-in assistant, Kenneth Iwamasa how to administer the drug, and provides ketamine to both Perry and Iwamasa at exorbitant prices. When the drugs become too expensive, Perry and Iwamasa turn to street dealers Assistant Kenneth Iwamasa reaches out to several street dealers. Eric Fleming agrees to a deal, and turns to his supplier Jasveen Sangha, dubbed “The Ketamine Queen.” Fleming pays Sangha for the drugs with cash from Iwamasa.
In two weeks, Sangha provides Fleming and Iwamasa 50 vials of ketamine to distribute to Perry for $11,000. When news of Perry’s death begins to circulate, Sangha texts Fleming, “Delete all of our messages.”
Now, Matthew Perry’s sisters, Caitlin and Madeline Morrison, speak out accusing assistant, Kenneth “Kenny” Iwamasa, accusing him of directly causing his death. The sisters described Iwamasa as someone Perry trusted and considered family. Madeline Morrison wrote that Iwamasa “had injected my brother with a lethal dose of ketamine and left him in a hot tub to die”, calling the betrayal “something I never could have conceived.” Caitlin Morrison echoed the sentiments, stating she could not determine if the lethal ketamine dose was accidental, but she knew Iwamasa was either “escaping from something he knew he had done” or “willfully abandoning a vulnerable person in a dangerous situation” when he left Perry.
Kenneth “Kenny” Iwamasa was sentenced on May 27, 2026 to 3 years and 5 months in federal prison and received a $10,000 fine. He was ordered to serve two years of supervised release after his prison term.
