AI-Generated Summary

This episode of Dateline True Crime Weekly covers three major true crime stories. First, the investigation into Gudrun Kasper Leinenkugel, a North Carolina woman accused of poisoning her daughter Lila and her daughter's boyfriend with cyanide-laced wine during a Thanksgiving dinner in 2025. Prosecutors allege she used acetonitrile—also linked to the 2007 death of a man named Michael Schmidt—suggesting a pattern of murder. Gudrun, who has a close relationship with her children, has pleaded not guilty and remains in jail without bond. Next, the case of D4VD (David Anthony Burke), a TikTok-famous singer arrested for the first-degree murder of 14-year-old Celeste Rivas, whose body was found in his Tesla trunk. Burke, 21, faces charges including premeditated murder, continuous sexual abuse of a minor, and body mutilation. He has pleaded not guilty, and his defense claims the evidence will prove his innocence. Finally, the episode highlights Sexual Assault Awareness Month with a powerful interview with Donna Palumba, a survivor who transformed her traumatic experience into advocacy through her organization, Jane Doe No More. She discusses the importance of victim support, education, and the long-term impact of re-victimization by authorities. The episode closes with a verdict in the Utah trial of Tracy Grist, who was found guilty on all counts for orchestrating the murder of her son-in-law.
