Nevada authorities on Friday identified a man they want to question as they search for a young girl shown being sexually assaulted in a homemade videotape.

Chester Arthur Stiles, 34, was being called a "person of interest" in the search for a girl with haunting eyes who authorities believe was 4 or 5 years old when she was raped and sexually assaulted in the video, Nye County Sheriff Tony DeMeo said.

The girl is called "Madison" on the tape, and it is "possible" that the man shown in it is Stiles, DeMeo said.

Stiles, whose last known address was Las Vegas, also was wanted on unrelated state and federal warrants on charges of sexual assault and lewdness with a minor under 14 years of age, the sheriff said.

"We know he has those warrants," DeMeo told The Associated Press by telephone from Pahrump, a rural town 60 miles from Las Vegas. "For us, he is a person of interest. We want to talk with Mr. Stiles about the identity of the female victim."

Investigators believe the tape was shot sometime since January 2005.

The Associated Press generally does not identify or release photos of suspected victims of sexual abuse but is doing so in this case in the interest of the girl's safe recovery.
