Less than 24 hours after Casey Anthony was found not guilty of killing her 2-year-old daughter Caylee Anthony, more than 45,000 have joined an online campaign calling for a federal law – named “Caylee’s Law” – that would make the failure of a parent to notify law enforcement of a child’s disappearance a felony.

The petition was created by Oklahoma woman Michelle Crowder, who said in a written statement: “I am hoping that this will be made into a federal law so that no other child’s life, disappearance, and/or death is treated in the manner that poor Caylee’s was treated. No child deserves that.”

The non-guilty verdict in the Casey Anthony case has shocked the world, and one of the main controversies of the case is the fact that Anthony never notified law enforcement that her daughter was missing (Caylee’s grandmother Cindy Anthony notified police one month later). Crowder and her tens of thousands of supporters want to ensure that this never happens again.

Nearly 4,000 people have commented on the online petition site so far: “It’s CHILD NEGLECT if you don’t know where your child is for a minute let alone 31 days!!! Don’t make more children suffer.. pass this law!!!” wrote on supporter. “This should already be a law. It’s too late for Caylee but maybe it will help save other children. God Bless Caylee Marie Anthony,” urged another.
