This is not an open homicide case. It was closed with Ms. Anthony's arrest. Law enforcement agencies do not reopen cases simply because a jury finds a defendant not guilty. Law enforcement has no reason to believe someone else murdered the child. In fact, it's debatable if the child was murdered since there was no physical evidence of foul play.
Cases are usually characterized as:
Open: An ongoing investigation. There may or may not be a suspect.
Open-inactive: There is nothing else to go on even if there is a suspect. This is typically seen in homicides since it has no statute of limitation (SOL). Some departments refer to these as "cold cases."
Closed: This is when a defendant has been arrested and there are not known to be other suspects. It is also used when the SOL has run because no prosecution is possible. If a suspect comes to light, then his name is added to the file, but nothing else occurs because the SOL bars prosecution.
There are no other suspects in the Anthony case. There are conspiracy theories, but the police aren't concerned about them.
The Anthony case is closed by arrest. The defendant was found not guilty and cannot be retried.
You haven't a clue who you're talking to.
