A South Setauket man pleaded guilty Monday to assault for the repeated abuse of his 5-week-old son in January 2024, according to Nassau County District Attorney Anne Donnelly.

Vincent Distasi, 33, was indicted in April 2024 for the attacks that caused extensive brain damage and required lifesaving surgery.

“Vicent Distasi is a sick and angry man who repeatedly beat up on his five-week-old son, filling that child’s first weeks on this earth with pain and violence,” Donnelly said. “When Distasi’s shocking, repeated abuse culminated in a near-fatal brain injury to his son and a trip to the emergency room, doctors horrifyingly discovered additional injuries, some already in the stages of healing, that told the full story of the disgusting abuse that this baby endured at the hands of his own father.”

Distasi is expected to receive 17 years in prison and five years of post-release supervision when he is sentenced. He is due back in court on Aug. 4.
