CASTAIC, Calif. (KNX) — Authorities searched in the area of the Chiquita Canyon Landfill in Castaic on Monday, part of an investigation into the disappearance of a woman reported last month.

Heidi Planck, 39, was reported missing by her ex-husband on Oct. 20. She was last seen Oct. 17 at an apartment complex in Downtown Los Angeles. Her dog was found in the same building, unattended, several hours later.

Planck was reported missing three days later after failing to collect her son from his West L.A. school.

"Forensic evidence was located inside the building which has led detectives to believe an incident occurred resulting in Planck’s death," police said of the complex at 1201 South Hope Street where the mother was last seen. On Nov. 4, her car was discovered in the underground parking garage of a residential building a few blocks away.

On Monday, authorities served a warrant to search the landfill at 29120 Henry Mayo Drive in Castaic, to “excavate a specific area of the landfill, manually search it for human remains, and collect any related evidence,” L.A. police said.

"It is anticipated this search and recovery operation could take approximately seven to 10 days to complete," police said. "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 LAPD has requested that anyone with information about Planck’s disappearance, including anyone who lives at 1201 South Hope Street, or who was in the vicinity of the building on Oct. 17, to call the Robbery-Homicide Division at (213) 486-6840. Tipsters wishing to remain anonymous can call the L.A. Regional Crime Stoppers at (800) 222-8477.
