Panebianco was sentenced to 25 years for first-degree manslaughter.

A sentence after a guilty plea is the judgment on the manslaughter count he admitted. It is not a murder verdict, and a co-defendant’s expected date is not this judgment. On Tuesday, Sept. 22, 2026, Victor Panebianco, 33, of King, North Carolina, was sentenced to 25 years in prison followed by five years of post-release supervision after pleading guilty Aug. 11 to manslaughter in the first degree, a class B felony, before Supreme Court Justice Timothy P. Mazzei. Kacy Corso’s expected seven years on Wednesday is her scheduled expectation, not a sentence entered today.

The victim is Christopher Millwater, 52. He was killed Nov. 10, 2025, in the parking lot of the Stony Brook Yacht Club in Suffolk County, on Long Island. Per the Suffolk County District Attorney and the admissions in court, Millwater arrived around 3:40 to 3:42 a.m. Panebianco and co-defendant Kacy Corso, 33, were waiting. Millwater tried to drive out. Corso crashed into his car and trapped him. He fled on foot. Surveillance, as described in those admissions, showed Panebianco chasing him while swinging a knife and stabbing him twice in the chest. Millwater died. The pair fled to North Carolina. That is the conduct behind the Aug. 11 plea. It is not a murder verdict returned on Tuesday.

Panebianco was arrested Nov. 19, 2025, in North Carolina, with help from the Stokes County Sheriff. Corso was later arrested in Suffolk. She pleaded guilty July 22, 2026, to first-degree manslaughter and is expected to be sentenced Wednesday, Sept. 23, 2026, to seven years. As of Tuesday’s sentencing, that seven-year figure is what is expected for her. It is not a judgment the court has imposed on her, and it is not a term in Panebianco’s sentence. District Attorney Raymond A. Tierney said the court imposed the maximum sentence his office requested and called the killing brutal. The New York Post reported Panebianco’s age as 32. The District Attorney's figure is 33. Five years of post-release supervision follows the 25 years. Supervision is part of his sentence. It is not a second case. Co-defendant Kacy Corso had not been sentenced, and she is presumed innocent until proven guilty in a court of law.
