(NORTH SALEM, NY) -- A Purdys man has been arraigned in a multi-count indictment alleging he took part in a series of sex assaults and attempted sex assaults in 2016 that included an attack on a woman at the Purdys train station. The charges were announced against 25-year-old Ronal Danilo Sandoval-Campos by Westchester County District Attorney Anthony Scarpino Jr. Sandoval-Campos has been charged with first degree rape, attempted rape, burglary, sexual abuse, criminal obstruction of breathing and unlawful imprisonment. Prosecutors say his first victim was a 42-year-old Mount Kisco woman who was home asleep June 3, 2016 in bed, when a male intruder broke in and raped her. He ran from the apartment, but left behind a gray hat he had been wearing. In the second instance, on August 21, 2016, a 19-year-old woman arrived at the Purdy’s Metro-North train station after spending time in New York City. As she walked through the stairwell and platform heading to the parking lot, she was approached by a man who attempted to engage her in conversation. He then followed her to a footpath leading to Route 116, grabbed her and pushed her to the ground. He groped her and tried to remove her clothing, according to prosecutors. A passerby heard her screams and was able to scare off the attacker. The man ran from the scene,also leaving his hat behind. Authorities conducted DNA testing on both hats and linked them to each attack as well as the suspect. Sandoval-Campos pleaded not guilty to the charges. He is being held without bail. If convicted, he faces up to forty years in state prison. His next court date is May 2.
