The Los Angeles Police Department’s search and recovery operation for missing person Heidi Planck continues at the Chiquita Canyon Landfill in Castaic, California. To date, more than 1,000 tons of waste and debris has been searched. Due to unforeseen forecasted weather events, the operation has been extended in order to complete the search of the area defined by the investigation. The LAPD greatly appreciates the continued patience and support of the community, especially the residents of Val Verde, as more than 60 detectives, police officers, criminalists and other experts continue the work of finding Heidi’s remains for her family.



Los Angeles: Detectives from the Los Angeles Police Department’s (LAPD) Robbery-Homicide Division are currently investigating the disappearance of Heidi Planck.

On October 20, 2021, Planck was reported missing by her ex-husband.

On October 29, 2021, Robbery-Homicide Division assumed investigative responsibility for the missing persons case. Since that time, detectives have worked tirelessly to gather leads related to Planck’s disappearance.

The investigation has revealed Planck was last seen on October 17, 2021, at an apartment complex at 1201 S. Hope Street, in the downtown area of Los Angeles. Her dog was found in that same building. Forensic evidence was located inside the building which has led detectives to believe an incident occurred resulting in Planck’s death.

On November 4, 2021, Planck’s 2017 Range Rover was discovered in the subterranean parking garage of a residential building located several blocks from 1201 S. Hope Street.

Further investigation has led investigators to the Chiquita Canyon Landfill, located at 29201 Henry Mayo Drive in the City of Castaic.

There is currently no suspect information.

This morning, LAPD detectives, along with the assistance of the Los Angeles City Department of Public Works, the Los Angeles City Fire Department, the Los Angeles County Department of Medical Examiner-Coroner’s Office, the Office of Los Angeles County Supervisor Kathryn Barger and the Los Angeles County Sheriff’s Department, are serving a search warrant at the landfill to excavate a specific area of the landfill, manually search it for human remains, and collect any related evidence.

It is anticipated this search and recovery operation could take approximately seven to ten days to complete. There may be an impact on community members who live around the Chiquita Canyon Landfill, specifically the community of Val Verde. Efforts are being made to minimize and mitigate that impact. We ask for the community’s understanding and support during this search and recovery effort.

The Los Angeles Police Department is requesting the community’s help. Anyone who lives in the building, or was around 1201 S. Hope, on or about October 17, 2021, and has any information that may assist detectives in their investigation, is urged to contact Robbery-Homicide Division at (213) 486-6840.
