JULIAN (CBS 8) - The family of a woman with Alzheimer's disease, who has been missing for six weeks, held a candlelight vigil to pray for her safe return.

Seventy-five-year-old Sally Estabrook has not been seen since October 4, when she disappeared from a campground in Julian. Hundreds of volunteers have spent days and weeks searching, but so far have turned up nothing.

But Saturday night's gathering in Julian demonstrated that so many are not giving up hope she'll be found and returned safely to her family.

Six weeks to the day that 75-year-old Sally Estabrook went missing from her campsite in Julian those closest to her, along with others dedicated to finding her, came together Saturday for an emotional candlelight vigil.

Estabrook, who suffers from Alzheimer's, had been camping at the Pinezanitas RV Park the afternoon of October 4, as her husband was taking a shower she apparently walked off, and seemingly vanished, leading to an intense and extensive search from air and on the ground by San Diego County's Search And Rescue team along with an army of volunteers.

A month and a half later, a committed core of searchers continued to scour the area.

One of the leaders in the continuing quest for answers, Carrie McGonigle the mother of kidnap and murder victim Amber Dubois, is appealing to residents to search their own properties for any sign of Estabrook.

"Especially up here in Julian, there are some huge properties. She could very well be on your property and you don't even know,” said McGonigle.

Estabrook's family believes a well-meaning driver who may now be afraid to come forward could have given her a ride.

Sally Estabrook is 5'4” and about 145 pounds, with shoulder-length blonde hair. She was last seen wearing a teal top and white Capri pants.
