WESTMINSTER, Colo. -
Investigators hope cell phone records could lead to a break in the search for the person who abducted Jessica Ridgeway.
ABC News reports that they're checking records of cell phone towers near Jessica's home, the location in Superior where her backpack was found and the park in Arvada where a body was found. If a phone registered at all three towers, it could lead to a suspect.
Sources tell ABC News the remains found Wednesday belong to Jessica Ridgeway, but police have said positive identification may not be available until at least Friday afternoon.
Jessica vanished on the morning of Friday, Oct. 5. She was last seen walking to Chelsea Park in the area of 107th Avenue and Moore Street around 8:30 a.m. where she was to meet several friends before walking to Witt Elementary School. Jessica's mother stood in the front yard of their home at 10768 Moore St. until her daughter was out of sight.
Thursday, the FBI released a general psychological profile of the man who took Jessica Ridgeway in hopes it would help the public look for possible suspects.
FBI spokesman Dave Joly said the suspect could "be your boss, your friend" or a family member.
The FBI Behavioral Analysis Unit said that often, someone in the community will unknowingly be associated with the offender of the crime, and may be in a position to observe behavioral changes in that person. They will recognize the changes, and may even question the person about it, but may not relate the changes to that person’s involvement in the crime. [Read the complete profile.]
Police said the parents are not suspects in Jessica's disappearance and have conducted extensive door-to-door searches in the area where she disappeared, in addition to using bloodhounds to try and pick up any direction for Jessica from her scent.
