Never saw one of these before.  Lis Pendens filed in 2005 on a residential property in Lynnfield , (held by an innocent seeming trust),  against various defendants, including the owner/trustee & other people not on  title  named "Fish", "Lefty" & "Sonny".  Restraining order  by US Attorney's office recorded 2006 alleging that "Fish" et als were engaged in racketeering, gambling, arson, extortion and money laundering.  Forfeiture under the RICO statute recorded in August 2010.   Oddly enough, this is a property where I did the title work on their last (pre-2005) refinance.
