A man wanted for raping a teenager has surrendered to police after living for nearly a month in the woods of Pennsylvania, eating worms and drinking from a creek to survive, a newspaper reported Wednesday.

Charles W. Lake, 39, had been sought by local and federal authorities since May 27, when police say he tied up, gagged and raped an 18-year-old woman at knifepoint inside her home.

Lake told police he heard police helicopters and felt compelled to surrender late Tuesday. He called 911 from a pay phone at a gas station and was taken into custody a few minutes later.

"He said, 'I knew you were looking for me, and I had nowhere to go,"' patrolwoman Alicia Hallinan, who interviewed Lake, told The Times-Tribune of Scranton. "'I have to face up to what I did."'

Lake told police he had been living in a cave in the woods and that he ate worms and drank water from a nearby creek to stay alive.

"What I did was wrong," he said early Wednesday as he was led from the district attorney's office, dressed in the same T-shirt and jeans he wore during the alleged rape.
