Mobster's Bones Found at Haunted Mansion?

An FBI search team descended on a famous "haunted" Staten Island mansion, locating possible remains of 2005 mob hit victim and Bonanno associate Robert McKelvey, sources said.

Bonanno capo Gino Galestro is awaiting trial on charges of ordering the hit; mob underling Joseph "Joe Black" Young is accused of carrying out the murder.

It was the second search for the feds at the mansion, once owned by brick baron Balthazar Kreischer.

The feds arrived with a dozen vehicles, including a truck from a septic-tank repair company.

The bone fragments must now be tested to confirm they belonged to McKelvey.
