Roy Barkin is one of two kidnappers and killers targeting the family of John Conlan, along with his cousin Nicky Costas. They were hired by Marty Dressler to kidnap his wife Alana and daughter Katie for a $15 million ransom.
The cousins killed housekeeper Isabel Paez and later also killed Alana, while Katie was rescued. Costas died while trying to escape with the ransom, so it was only Barkin and Dressler were arrested.
They were briefly released after a mistrial, until Conlan finally testified he caused a blackout from fraud the kidnappers exploited, resulting in their imprisonment. (L&O: “Darkness”)
