 The bodies of a 36-year-old woman and a young boy were found inside a Manhattan apartment Monday morning, police say. The 36-year-old mother and Afghanistan War veteran was found dead Monday morning in the living room of her Manhattan apartment, according to the police source, who confirms that she was strangled with an electrical cord and Miguel was drowned in the bathtub. The report indicates that Ms. Barahona had been his teacher. The report says that Barahona later invited Duran to her home on his birthday, where they had the first of what would be several sexual encounters. A source told NBC 4 New York that Duran Infante, of Bethlehem, Pennsylvania, confessed to the double killing in part because he was dissatisfied with the way his son was being raised by Barahona.
– A man who as a teenager had an affair and subsequent child with his high school science teacher is now accused of killing them both. A building superintendent alerted to a foul smell found Felicia Barahona, 36, strangled with an electrical cord in her Manhattan apartment on Monday, while Barahona's 4-year-old son, Miguel, had been drowned in a bathtub, reports People. Miguel's father, Isaac Duran, 23, was arrested later Monday and initially denied any involvement, saying he hadn't been to Barahona's apartment since their son was born. However, police sources say Duran "owned up" to the murders after police found surveillance video showing him entering and exiting the building on several occasions, reports the New York Post. He was charged Tuesday with two counts of first-degree murder, reports the New York Times. Duran and Barahona had started a relationship in 2011, reportedly after Duran turned 18 but while Barahona was his teacher at DeWitt Clinton High School in New York City. Barahona, who was later fired, became pregnant, though her relationship with Duran ended before Miguel was born in 2012, per DNAInfo. Duran had shared custody of Miguel, relatives tell NBC News, but he was reportedly angry about how Barahona was raising the boy. His half-brother tells the Times of frequent arguments. “It was over who gets the kid, how do we figure out what payments are done, if he’s going to pay support or not."
