Heidi Planck, a 38-year-old mother from Los Angeles, was last seen on October 17, 2021, after leaving her son's football game in Downey, California. Later that day, security footage captured her walking her dog near an apartment complex in downtown Los Angeles. Her dog was later found wandering inside the building, but Heidi vanished without a trace. Investigations uncovered forensic evidence in the building suggesting foul play, but no remains have been found.
