Vital Statistics

Circumstances of Disappearance:

On October 17, 2021, Planck left home with her dog Seven to drive to Downey. She attended her 10-year-old son's football game, during which she was described as distracted and bothered. Around 4:30 pm, she told her ex-husband she had to leave early and drove away before the game was over. Soon after the game ended, she sent a text message to her son congratulating him on his win. Around 6:30 pm, Planck was captured on security footage walking her dog outside a downtown Los Angeles apartment complex. She never returned home that evening and has never been heard from again. Around 7:00 pm, her Labradoodle dog Seven was discovered wandering alone on the 28th floor of Hope + Flower, a luxury apartment complex at 1201 South Hope Street, with no signs of Heidi Planck. On October 20, 2021, Planck's ex-husband became concerned after she failed to pick up their 10-year-old son at his private school in Westwood and filed a missing persons report with the Los Angeles Police Department.

Additional Details:

On October 29, 2021, the FBI served a search warrant on Heidi Planck's home with guns drawn, expecting to find a crime scene, but found no sign of her. They found her cell phone and laptop, but her car and dog were missing. Her phone record, bank account, and social media have shown no activity since she disappeared. On November 4, 2021, her silver 2017 Range Rover with California license plate U840X0 was found abandoned in the underground garage of a residential building located a few blocks away from Hope + Flower. Forensic evidence was located inside the building which led detectives to believe an incident occurred resulting in Planck's death. On November 29, 2021, authorities executed a search warrant at the Chiquita Canyon Landfill, located on 29201 Henry Mayo Drive in Castaic, about forty miles northwest of Los Angeles. More than 1,000 tons of waste and debris has been searched. Law enforcement sources indicated that there was information suggesting Planck may have met up with one or more people attending a poker game that day or had visited the apartment where it was being held before she vanished. Jason Sugarman, a part owner of the LA soccer team who is married to the daughter of Dodgers owner Peter Guber, was swept up in an ongoing Securities and Exchange Commission investigation into an elaborate scheme that defrauded a Native American tribe of the Sioux Nation out of $43 million, with Sugarman slated to go on trial in Manhattan's Southern District on civil charges connected to the fraud. In February 2023, Planck was officially declared dead by a court ruling, with a judge ruling that Planck's official date of death was the night she disappeared on October 17, 2021. For a second year in a row, family and friends of Planck got the missing mom's face up on several LA billboards for the month of October and set up a #FindHeidiPlanck website to provide information about the case and ask the public to submit tips. LAPD stated it is confident there are four or five people that know exactly what happened to her.
