(CBS SF) — A 15-year-old Mississippi girl is suspected of calling in a bomb threat to Wilkinson School in El Granada Thursday in the mistaken belief that she was targeting her own similarly-named high school.

The girl reportedly called in the threat at about 10 a.m.  Thursday, prompting a campus-wide evacuation and a thorough search by the San Mateo County Sheriff’s Department bomb squad.
