With the manhunt in Big Bear Lake for ex-cop Christopher Dorner coming up empty so far, authorities are admitting they have no idea where Dorner is, reports Fox News. Thousands of police officers are now involved in the hunt, in California, Nevada, Arizona, and northern Mexico. "He could be anywhere at this point," says the San Bernardino county sheriff. Meanwhile, the AP reports that as many as 16 San Diego County sheriff's deputies spent the night surrounding and searching a rural home after a hoaxer reported Dorner was there. There were people at home but Dorner wasn't one of them. Investigators have a pretty good idea who made the call and will seek criminal charges.
