Long Island is dealing with a tough loss right now. Victoria Castle was a bright 25-year-old PhD student at Stony Brook University. She had a massive future ahead of her in the science world. But everything cut short on Monday morning, June 29, 2026. She was found unresponsive inside her home, leaving her family and classmates completely heartbroken.
Victoria was the kind of person everyone loved to be around. Her professors and friends say she was incredibly smart and driven. She spent hours doing research in the geology lab but always made time to help others. Outside of school, people knew her for her huge heart and sweet personality. She had this rare ability to make anyone feel important.
She lived in a quiet neighborhood on North Oak Street in North Massapequa. Her living setup was close-knit. She stayed in the ground-floor apartment of a two-family house. Her sister lived right upstairs with her husband, Joseph Horner. It seemed like a safe, normal family arrangement until things went terribly wrong.
The tragedy happened while Victoria’s sister was out of town for a bachelorette party. Prosecutors say Horner asked Victoria to come help him move a piano. It was a simple favor for a family member. But once she was inside, police say Horner ambushed her from behind and put her in a deadly chokehold.
After the assault, Horner dialed 911 to report that a woman wasn’t breathing. Emergency workers rushed to the North Massapequa home around 8:45 a.m. and tried to save her with CPR. They quickly transported her to a nearby hospital. Sadly, doctors pronounced her dead a short time later.
Now, her family and friends are trying to focus on the good times. They want to remember how Victoria lived instead of how she died. People are looking back at old social media posts she wrote. One sweet message celebrating her sister’s wedding stands out, showing just how much she loved her family.
Tributes are pouring in from all over the Stony Brook campus. Classmates and colleagues are sharing their favorite memories of her warmth and brilliant mind. Victoria will always be remembered as a wonderful daughter, sister, and scholar. Her impact on the world will definitely stick around for a very long time.
