Long Island Music Teacher Charged With Murder And Rape In Death Of Sister-In-Law
A Long Island music teacher has been charged with murder and rape following the death of his 25-year-old sister-in-law, a case that prosecutors say unfolded while the suspect’s wife was away from home.
Joseph Horner, 27, was arrested after authorities say he called 911 to report the incident at a multi-family residence in North Massapequa, New York. Prosecutors allege Horner attacked Victoria Castle inside the home before contacting emergency services. Horner has pleaded not guilty to the charges and remains presumed innocent unless and until proven guilty in court.
According to the Nassau County Police Department, officers responded to a residence on North Oak Street at approximately 8:45 a.m. Monday after receiving a 911 call.
When officers arrived, they found Castle critically injured inside the home. Emergency medical personnel transported her to a nearby hospital, where she was pronounced dead less than an hour later, authorities said.
Horner was taken into custody at the scene without incident.
According to prosecutors, Horner lived in an upstairs apartment of the residence with his wife, while Castle occupied a separate apartment on the ground floor.
Investigators allege Horner’s wife was out of town attending a bachelorette celebration when the incident occurred.
During Horner’s arraignment, prosecutors outlined the allegations supporting the charges.
According to the Nassau County District Attorney’s Office, Horner allegedly asked Castle to assist him with moving a piano before attacking her inside the residence. Prosecutors allege he placed Castle in a chokehold until she became unconscious and then sexually assaulted her.
The allegations presented during the arraignment represent the prosecution’s version of events and have not yet been proven in court.
Authorities further allege that after the incident, Horner contacted emergency services and remained at the residence until officers arrived.
According to prosecutors, Horner made statements to investigators after police responded. The admissibility and significance of those statements, if any, will ultimately be determined through the judicial process.
Prosecutors also alleged during the arraignment that Horner had been attracted to Castle for several years after first meeting her through his future wife.
Those assertions form part of the prosecution’s case and will be subject to examination during future court proceedings.
Horner has been charged with second-degree murder and rape.
Following his arraignment, a judge ordered that he be held without bail pending further proceedings. Horner entered a plea of not guilty to the charges.
The case will continue through the New York criminal justice system, where prosecutors bear the burden of proving each allegation beyond a reasonable doubt.
Castle was pursuing a doctoral degree at Stony Brook University at the time of her death, according to prosecutors.
Friends and family have begun mourning the loss of the 25-year-old, whose death has shocked those who knew her and the wider Long Island community.
Following Horner’s arrest, the Oceanside School District confirmed that he had been placed on administrative leave from his position as a music teacher.
In a statement, school officials said they were aware of the charges and were cooperating as appropriate while expressing sympathy for the victim’s family.
Legal experts note that information presented during an arraignment is intended to establish probable cause for the charges and should not be interpreted as a final determination of guilt.
The prosecution’s allegations will be tested through future hearings and, if the case proceeds to trial, before a jury or judge.
Investigators continue processing forensic evidence and reviewing all aspects of the case as prosecutors prepare for the next stage of the proceedings.
Authorities have not indicated whether additional charges may be filed.
For Victoria Castle’s family, the criminal case begins as they mourn the loss of a daughter and sister whose life ended under tragic circumstances.
As the judicial process moves forward, the court will ultimately determine whether the prosecution has proven the charges against Horner based on the evidence presented. Until then, the defendant remains entitled to the presumption of innocence under New York law.
