Dateline NBC “After the Storm” June 21 2025 Recap & Preview

A Dateline Weekend Mystery airs Saturday, June 21, 2025, at 9/8c on NBC. Titled After the Storm, the episode is reported by Keith Morrison and tells the unsettling story of Diane Holik, a successful, vibrant woman whose life was cut short in a brutal and calculated crime inside her Austin, Texas home.

 Diane Holik was in the middle of planning a new chapter. She was preparing to sell her home and move to Houston to live with her fiancé. But before that dream could become reality, she was found strangled to death. As police began their investigation, they initially focused on the men in Diane’s life — those closest to her. But as each person was ruled out, a more chilling possibility came to light: a stranger may have committed the murder.

The case took a major turn when police learned that Diane had been showing her home to potential buyers. Around the same time, multiple women came forward to report disturbing encounters with a man who had been posing as a buyer or renter. These women described eerie, unsettling behavior that raised red flags. Investigators eventually connected these reports and uncovered a predator who used real estate listings as a way to target victims.

Dateline’s After the Storm offers a detailed look at how detectives unraveled the mystery and brought justice to Diane’s family. With exclusive interviews and Keith Morrison’s signature storytelling, this episode revisits a case that left a community shaken and forever changed.
