The search for a missing 14-year old California girl was called off as it entered its sixth day Thursday.

The family of Amber LeeAnne DuBois said the teen was last seen shortly after 7 a.m. Friday while walking to Escondido High School.

Investigators have learned that DuBois talked to a friend on her cell phone on her way to class that morning, San Diego radio station KFMB reported.

Witnesses claimed to have spotted her in downtown Escondido Saturday and Sunday nights.

The teen's father, Maurice DuBois, said reports of a possible sighting of his daughter Saturday were considered unreliable. He said his daughter is very structured — not the type of girl to disappear on her own.

Police have decided to wait to get better leads before resuming the search, KFMB reported.

Meanwhile, family members have set up a Web site with pictures and contact information for the missing girl, and are pushing for the search to go nationwide.
