Police in California have found the cell phone of a missing teenager who was last seen leaving her house on her way to school.
On Friday the mother of 15-year-old Sierra Lamar said goodbye to her daughter at around 6am before her half-mile walk to the bus stop. The driver and fellow students said she never got there.
Her cell phone was found in a field a few miles from her house.
The Santa Clara Sheriff's Department said police dogs lost her scent in the driveway of her house, so they have suspended the search around the house and are now focusing on her school and her classmates.

"We have exhausted our search efforts in that area. We have investigators talking to kids hoping they can lead us in the right direction as far as where she could be. We are looking for any information period," Sgt. Jose Cordoza told ABC News.
Her family said there is no chance that Sierra would run away. There appears to be no problems in her home life.
"We're hoping she's alive and that's the most important thing right now,' her mother Marlene Lamar told KTVU-TV.
