By M. William Phelps

This Fall Phelps will embark on the story behind the murder of Jeanne Dominico, the Nashua, N. H., woman killed Aug. 6, 2003, by Willimantic resident William “Bill” Sullivan.

Sullivan, at 18, was convicted of murdering Dominico, 43, the mother of his then 16-year-old girlfriend, Nicole Kasinskas, whom he met online.

Phelps said, “One of the most compelling aspects of the story for him is the love triangle. From one perspective, you have a mother and daughter who friends and family say loved each other deeply, and, from the other, a sociopath boyfriend whose selfishness, jealousy and rage tore all their lives apart.”

Sullivan, a Willimantic resident, was convicted of first-degree murder and conspiracy to murder after a July 2005 trial for brutally stabbing and bludgeoning Dominico to death in her home. He saw her as standing between him and her daughter. Sullivan is serving life in prison without the chance of parole.
