About this episode

The episode discusses the mysterious disappearance of Heidi Planck after a football game and the clues surrounding her case.

Heidi Planck, a 38-year-old finance professional and mother, disappeared after attending her son’s football game in October 2021, sparking concern due to disabled location tracking on her devices and unusual behavior. Days after her disappearance, her dog would be found wandering around the 28th floor of a downtown-L.A. high rise building. Was this an important clue about what might have happened to Heidi the night she went missing? Or was there something more sinister at play? This is her story. If you know something about Heidi’s disappearance, call the LAPD at 213-486-6840. There’s also an anonymous tip line—the Los Angeles Regional Crime Stoppers at 1-800-222-TIPS (8477).
