Caylee 's Law is the unofficial name for bills proposed or passed in several U.S. states that make it a felony for a parent or legal guardian to fail to report a missing child , in cases where the parent knew or should have known that the child was possibly in danger . The first such bill was introduced shortly after the high-profile Casey Anthony trial , due to Anthony not reporting her two-year-old daughter Caylee Marie Anthony missing for a period of 31 days
