Kuklinski was kept in Bergen County Jail in NJ in solitary confinement . </P> <P> In October 2005, after 17 years in prison, Kuklinski was diagnosed with a rare and incurable inflammation of the blood vessels and was transferred to a secure wing at St. Francis Medical Center in Trenton, New Jersey .

A week before his death, the hospital called Barbara to ask if she wished to rescind the instruction, but she declined . Kuklinski died at age 70 on March 5, 2006 . His body was cremated . </P> <P> Michael Shannon plays Kuklinski in the 2012 film The Iceman based on Anthony Bruno's book The Iceman: The True Story of a Cold - Blooded Killer .
