The friends and family of Heidi Planck aren't giving up hope, even weeks after she vanished.

LOS ANGELES - It’s been three weeks since Heidi Planck went missing, but her family and friends aren’t giving up hope.

On Sunday, her family held a candlelight vigil in downtown Los Angeles, hoping to find more clues in her disappearance.

Planck's family reported her missing to the Los Angeles Police Department on Oct. 20 after she failed to pick up her 10-year-old son from school. However, she was last seen on Oct. 17, when she abruptly left her son's football game in Downey before it was over.

Days after she went missing, her dog was found roaming on the 28th floor of a high-rise residential building in downtown LA.
