Police say 36-year-old Roberto Villavicencio was charged with first-degree criminal impersonation of a police officer and endangering the welfare of a child.
State Park police were called to the area when the girl was reported missing. She was found in parking Field 4 and told investigators that Villavicencio told her he was a police officer and had her accompany him to his car, where he could show her his identification.
Authorities say Villavicencio made "inappropriate sexual inquiries" to the girl on the way to the car.
State Park police ask anyone with additional information to call detectives at 631-321-3700.
