A jilted and jealous Hispanic fatally stabbed the mother of his infant daughter after a high-speed Bronx chase and crash that pinned her inside a crumpled SUV

Battered ex-girlfriend Katherine German, 20, was stalked by the deranged Latino and brutally slashed shortly after he spotted her leaving a nearby motel with another man. German’s blood was spattered across an air bag during the vicious killing that followed a terrifying wreck off the Pelham Parkway. Spurned boyfriend Doines Espinal — who had a violent past and a festering grudge against his ex-lover — was waiting in the darkness outside the $40-for-four-hours Paradise Motor Inn. “He said he was going to kill her,” said the dead woman’s heartbroken mother, Fernanda Rivera. “He threatened to kill her twice ... All the time he would follow her, where she was going, who she was talking to.” Espinal, 31, stabbed German repeatedly in the neck and torso as her date watched helplessly. She died inside the Honda Pilot SUV. Espinal waited at the gruesome crime scene until police arrived and arrested him. He was charged with murder and quickly lawyered up without making any statements to cops. The couple began dating about three years ago, and their daughter Audrey was born July 24, 2013. “They were fighting over the baby,” said Rivera, describing the couple’s rocky relationship. “He was persecuting her all the time. He was very jealous.” German got an order of protection against her boyfriend in May 2013, charging the volatile Espinal with assault, menacing and harassment. Espinal, a cab driver, knocked her to the floor with a punch to the face, then jumped on top of German and landed several more close-fisted blows, court records show. German was hospitalized with lacerations to her forehead, eye, nose and lip.
