Crews from the Orange County Sheriff's Office are back at the home of 2-year-old Caylee's grandparents today to search for more clues in the girl's disappearance. They dug in the backyard yesterday after cadaver dogs alerted on certain areas.

Sergeant John Allen says the grandparents are not suspects.

"This child's grandparents have been very cooperative with us. They seem very concerned about their granddaughter. I think that more than anything, they want us to find that child and return the child to them."

A neighbor gave deputies a tip to led to the search. She said the child's mother Casey borrowed a shovel from her. That shovel has been taken into evidence, as well as a computer belonging to Anthony. She remains in jail without bond, held on child neglect charges.
