In a shocking incident that has rattled the community of Stony Brook, Long Island, a woman has been charged with second-degree murder following the brutal stabbing of her former boyfriend, Christopher Milwater. The alleged crime occurred in the early hours of November 10, 2025, outside the Stony Brook Yacht Club, where Milwater was reportedly attacked by Casey Corso and her current boyfriend, Victor Payne Biano.
According to law enforcement, Milwater, a well-liked figure known for his passion for fishing, was stabbed multiple times in the heart and lungs after being confronted by Biano. Prosecutors claim that Corso played a crucial role in the incident by blocking Milwater’s vehicle with her own, preventing his escape. The circumstances leading to this violent act remain unclear, but social media posts from Corso provide some insight into her tumultuous relationship with Milwater.
In the months leading up to the murder, Corso posted several cryptic messages on Facebook that hinted at deep-seated anger and resentment towards Milwater. In one post from July, she described the end of a relationship, suggesting that the true nature of a partner is revealed when the facade fades. On July 26, she accused Milwater of being a “grave robber,” indicating a troubling dynamic between the two.
Milwater’s last social media activity was a video he shared just 48 hours before his death, in which he appeared relaxed and engaged in a product promotion. Friends and family have expressed their shock at the news of his murder, remembering him as someone who was always there for others. A GoFundMe campaign has been launched by his sister to cover funeral expenses, reflecting the family’s grief and need for support during this difficult time.
Authorities have indicated that the investigation is ongoing, with evidence suggesting potential premeditation behind the attack. The specifics of how the confrontation escalated remain a focal point for investigators, and it is believed that surveillance footage from the yacht club may provide critical insights into the events that transpired that night.
Both Corso and Payne were quickly apprehended following the incident, with Corso being taken into custody shortly after returning from a trip to North Carolina. They are currently awaiting trial, and the legal proceedings are expected to unravel further details regarding the complicated relationship dynamics that may have led to Milwater’s tragic death.
As the case progresses, the community is left grappling with the senseless violence that has claimed a life and shattered families. The circumstances surrounding Christopher Milwater’s death serve as a grim reminder of the potential consequences of unresolved personal conflicts. The legal system will now play a crucial role in determining the accountability of those involved in this tragic incident.
