Florida investigators ended their search Saturday of the woods where Caylee Anthony's body was found and then served a warrant at her grandparents' home.

Capt. Angelo Nieves of the Orange County Sheriff's Department said "items of evidentiary value" were found in George and Cindy Anthony's house, the Los Angeles Times reported. Nieves refused to say what was in the two boxes and bags taken out of the house.

Caylee's skeletal remains were found less than half a mile from the house 10 days ago. Authorities announced Friday that the remains had been positively identified as the missing 2-year-old.

Visitors put flowers and stuffed animals on an informal memorial nearby.

"I can't comprehend it with Caylee, or with any child," said Kitty Bowersock of Winter Park, Fla., who brought three roses. "I'm shaking right now."

Caylee's mother, Casey Anthony, reported her daughter missing in July, saying she had been kidnapped by a babysitter a month earlier. Casey Anthony has been charged with murder and is in jail.
