Alan Vasquez-Alarcon faces multiple felony sex charges following a joint investigation by Spring Valley and Ramapo police that included a missing juvenile case.
An 18-year-old man has been arrested and charged with multiple felony sex offenses in connection with alleged sexual encounters involving three 13-year-old girls, including one who had been reported missing, according to police.
Alan Vasquez-Alarcon was taken into custody following an investigation conducted by the Spring Valley Police Department and the Ramapo Police Department, Detective Sgt. Randy DiPaolo said.
Police said the investigation began in September. On September 30, officers from both departments launched a joint sexual assault investigation after receiving information concerning Vasquez-Alarcon and one of the girls.
According to investigators, the inquiry determined that Vasquez-Alarcon allegedly engaged in a sexual relationship with the juvenile in both Spring Valley and Ramapo.
The investigation expanded on October 6, when Spring Valley police became involved in a missing-person case concerning a second 13-year-old girl. Investigators subsequently learned that she may also have been involved in an intimate relationship with Vasquez-Alarcon, police said.
Officers went to a residence on Lafayette Street in an attempt to locate Vasquez-Alarcon and the missing juvenile. When police arrived, Vasquez-Alarcon allegedly fled the residence but was quickly apprehended. The missing girl was subsequently found inside the residence, according to DiPaolo.
Further investigation led detectives to conclude that Vasquez-Alarcon had allegedly engaged in sexual intercourse with the second juvenile, police said.
Detectives also uncovered a third case involving another 13-year-old girl. Investigators located the girl and determined that she had allegedly been sexually assaulted by Vasquez-Alarcon, according to police.
During the investigations, detectives also learned that Vasquez-Alarcon allegedly presented himself as younger than his actual age, police said.
Vasquez-Alarcon was arraigned in Spring Valley Justice Court before being transferred to the Rockland County Jail.
Police are asking anyone with information related to the investigation to contact the Spring Valley Police Department at 845-356-7400 or email tips@villagespringvalley.org.
