Police Detail Boy's Escape In Fla. Kidnapping AttemptMIAMI --A 13-year-old boy bound to a tree in the woods foiled a kidnapping-for-ransom plan by using a safety pin, his teeth and his hands to escape, police said Sunday.

Investigators searched a house in Bradenton, Fla., and issued an arrest warrant for Vicente Ignacio Beltran Moreno, 22. Authorities think he has fled the state.

The truck that police think was used in the kidnapping was found outside the home believed to be Beltran's, detectives said. They also found a ransom note with threats.

On Friday morning, about a dozen children at a school bus stop watched as Clay Moore was forced at gunpoint into a red pickup truck, police said. He apparently was chosen randomly from the group in Parrish, a town about 30 miles southeast of St. Petersburg that has experienced explosive growth but still has many rural areas, authorities said.

Clay was bound and left alone about 20 miles away in dense woods on a farm where Beltran had worked three years ago, police said.

For several hours, the boy worked to untie himself, then walked until he found a farmworker with a cellphone, police said.
