Joseph Horner, 27, was best known in his Long Island, New York, neighborhood as a tenured elementary school music teacher. Now, Horner is facing second-degree murder charges after his sister-in-law was found dead at their home.
According to People, prosecutors allege that Horner fatally strangled 25-year-old Victoria Castle on the morning of June 29. Horner and Castle reportedly lived in the same North Oak Street housing complex in North Massapequa. Horner and his wife lived in the upstairs unit, while Castle lived in a ground-floor apartment.
