Florida officials say they will no longer follow any tips that missing toddler Caylee Anthony is still alive.
The child's mother, Casey Anthony, has pled not guilty to charges of first-degree murder, aggravated child abuse, and aggravated manslaughter.
Anthony is charged with four counts of lying to investigators about the disappearance of her daughter.
Investigators are concerned that a continued search would help Casey's defense team establish reasonable doubt about Caylee's murder.
That's not sitting well with some family members, like Casey's mother.
She says she believes her granddaughter is still alive.
