The man is described as older, with short gray hair.

The girl said she saw him at least once before when she refused his offer for a ride. This time though, she said he got out of his car, grabbed her around the waist and attempted to force her into his vehicle. She was able to break free and run home.

The man then got back into his car and drove away from the scene. He was driving a small, silver four-door sedan with large rust spots, especially on the trunk. The vehicle did not have license plates on it during the abduction attempt.
