Andrew Ostroy, with whom Shelly had a young daughter, Sophie, addressed Diego Pillco, 21, who was sentenced in State Supreme Court in Manhattan to 25 years in prison, The New York Times said Friday.
Ostroy, speaking at the sentencing Thursday, called the "Waitress" filmmaker the"love of my life" and said Pillco sentenced their daughter "to a lifetime of anguish and sadness and questions and feelings of what could've been," the Times reported.
"No sentence would be enough for you," he said. "I want you to suffer like she suffered, to live a life of fear, the same fear she felt when she realized she was about to die."
Shelly's mother, Elaine Levine, also expressed her heartbreak and told Pillco she couldn't forgive him for what he had done.
Pillco, an illegal immigrant from Ecuador confessed he strangled Shelly in 2006 when she caught him stealing money out of her purse in a Manhattan apartment she used as an office.
The sentence was part of a deal in which Pillco agreed last month to plead guilty to manslaughter.
