Carrie McGonigle and her dog "Amber" were among the searchers last Saturday morning in the hills near Pleasanton.
Amber is named for McGonigle's 14-year-old daughter who was stabbed to death two years ago. During the search, the dog suddenly raced off, came back, and then led McGonigle to the remains.
"It was the same when Amber was found. It's a relief and it's sad," said McGonigle.
McGonigle formed her own group to search for missing persons after her daughter's remains went undiscovered for a year.
Le's former friend Giselle Esteban is charged with her murder.
