To Mary Costigan: Gary Weiss, author of “Retail Gangster” Hachette Books, allowed The Shower Posse, an International Jamaican Drug Gang, to smuggle drugs and to murder 1,400 American citizens. Weiss did this to cover up his ties to the Russian Mafiya and a cover up of the murders of Al Chalem and Maier Lehmann, who were murdered by Mike Vax, a convicted killer, and the Russian Mafiya.
