American serial killer Richard Kuklinski and wife Barbara had three children together: Merrick, Christin and Dwayne.
Most recent news from The Telegraph reported that Barbara Kuklinski was living in a small apartment in the basement of a white shingled house in suburban New York State, which she shares with her younger daughter Christin and her boyfriend, and three dogs.
The true story of the notorious mob hitman had a film adaptation (released in 2013) starring Michael Shannon.
While it was previously reported that Merrick has a number of health problems and is reclusive, Shannon had a chance of meeting the real life daughters of the contract killer saying that it was "moving" to meet them.

The children are in their 50’s and late forties now, with no update on Dwayne Kuklinski.
Barbara is in her 70s now. She suffers from arthritis of the spine and a cluster of other chronic illnesses which she believes stem from the years she spent living in the shadow of her husband; a nurse visits once a week. After her husband’s arrest he left her with nothing and she was forced to look to her children for support.
