A 16-year-old girl being treated for anorexia and other psychological disorders is missing.
Amy Richards ran away from the treatment facility on Shadow Run Road early Tuesday morning. The home is operated by Summitview Child & Family Services.
Sheriff's investigators learned the teen had stuffed her bed to make it look like she was asleep in it and the screen was removed from her bedroom window.
The 16-year-old left a note saying she would be OK but it was believed she had neither money nor a cellphone with her.
Amy's family has not heard from her. They live in San Francisco and there is the possibility she may be trying to get there.
Search crews are plastering fliers with Amy's picture on it all over Placerville. They are hoping someone will recognize her.
Her father drove up from San Francisco to help find her.
"I'm just terrified for Amy's safety in general," Don Richards said.
The missing girl is described as white, 5 feet 5 inches tall and weighing approximately 100 pounds. She has blue eyes and waist-length blond hair. There are more than 30 scars on her inner forearm from cutting.
There is concern for the teen's welfare because she had been refusing her medication and had lost more weight, the sheriff's report said.
"She's severely anorexic and has a very low heart rate," Executive Director Anna Gleason said.
The longer she's missing, the more worried her father becomes.
"Hours or days are literally all she can survive without medical care," Richards said.
It wasn't known what Amy was wearing when she left but when last seen, she had on a t-shirt and jeans. She may have a light-blue satchel-style purse.
The El Dorado County Sheriff's Office used search dogs to look for Amy Thursday morning. Officials didn't know if she went in the woods or stayed on Mosquito Road. They say the dogs indicated she likely stayed on the road and kept walking.
"It's hard to know whether she walked away or was picked up by an accomplice trying to help her," Gleason added.
Her father has started a Facebook page to help spread the word about her disappearance.
He had a message for her Thursday night.
"Amy, be safe. Make yourself safe," Richards implored. "Contact someone you trust and know that you will be listened to."
Any sightings or information on Richards' whereabouts can be reported to El Dorado County sheriff's dispatchers at (530) 621-6600 or Det. Rich Horn at (530) 642-4715.
