My seventeen year old daughter went to school on Tuesday morning and has yet to return. According to the authorities, this is by choice, because she was seen around 2 p.m. Tuesday with friends and has called/txt her friend on several occasions from this number. It is an unlisted Nextel cell number. I need to know who this number belongs to; I'm concerned that an adult, that she met online, may be harboring her. She has never ran away before.
