A woman's ex-boyfriend was charged with murder after she was found stabbed to death at the Belmont Racetrack, police and track workers said.
Security noticed a horse was loose and became alarmed early Sunday morning, Nassau County police said. Security officers entered a barn and found a woman who had been stabbed multiple times.
The 51-year-old victim was brought by ambulance to a local hospital where she was pronounced dead, police said. Her identity hasn't been released.
Jose Franco-Martinez, 53, was taken into custody at the racetrack and has been charged with second-degree murder, according to police.
A Nassau County detective said the victim worked as a "hot walker," walking horses after training sessions.
Workers at the track on Sunday told NBC New York that Franco-Martinez was the victim's ex-boyfriend. He had worked at the track until he moved to another state, they said.
An investigation is ongoing.
Just a week earlier, Belmont was the site of the final race won by Justify as he clinched the Triple Crown.
