The teens were reported missing at about 6:10 p.m. from the Log Cabin Ranch School, a San Francisco Juvenile Probation Department detention facility at 500 Log Cabin Ranch Road in La Honda, San Mateo County sheriff's Lt. Ray Lunny said.
They were last seen by staff getting into a blue or aqua-colored car similar to a Toyota Corolla just down the hill from the facility, according to Lunny.
Lunny described the area as remote and said it would be difficult to run away on foot.

The other is 16, about 5 feet 6 inches tall and 110 pounds. He also has black hair and brown eyes and was last seen wearing a white T-shirt, khaki pants and white tennis shoes.
