Long Island music teacher rapes, strangles sister-in-law he lusted over for years with wife out of town: prosecutors
A Long Island music teacher sexually assaulted and strangled his sister-in-law — whom he’d reportedly been lusting over for nearly a decade — while his wife was away on a bachelorette trip, according to police and prosecutors.
Joseph Horner, 27, killed Victoria Castle, his wife’s 25-year-old sister, at their shared North Oak Street home in North Massapequa and then called the cops on himself around 8:45 a.m. on Monday, the Nassau County Police Department said.
Horner – a music teacher in the Oceanside School District – lived in the upstairs apartment of the multi-family house with his wife, and Castle lived in the ground-floor unit, according to the Nassau County District Attorney’s Office.
While Horner’s wife was out of town for a bachelorette party, he took advantage of her absence to act on sick urges he had for her sister – whom he’d lusted after since 2017, prosecutors said at his arraignment.
