Marco Island police Capt. David Baer says the vandals also left at least seven pickled pigs' feet on the driveway of Walter Palmer's $1.1 million home. Baer says police have opened an investigation.

A hand-made sign criticizing Palmer was left in the yard last week. A security company has been hired to protect the property.
