Heidi Planck remembered by family, friends 6 months after mysterious disappearance in downtown LA

LOS ANGELES -- Friends of Heidi Planck are remembering the missing local mom six months to the day after her disappearance.

The 39-year-old went missing last October under mysterious circumstances.

Los Angeles Police Department detectives told family and friends that an incident at a downtown L.A. apartment building in October resulted in her death.

Questions remain about why Planck was at that high-rise where her dog was found wandering on an upper floor.

A search at a Castaic landfill for her remains didn't turn up anything conclusive.
