AMES, Iowa (AP) _ A man and two teens have been arrested on suspicion of abducting a 17-year-old Hamilton County girl from her backyard, driving her to an Ames park and raping her. The Story County Sheriff's office says deputies arrested a 20-year-old man and 16-year-old boy, both from Ames, as well as a 16-year-old boy from Boone. Deputies found the three and the truck believed to have been used in the abduction and assault soon after someone reported seeing the 17-year-old girl emerge from a wooded area of the park Thursday afternoon asking for help. The girl told investigators she had been hanging clothes in her backyard when the three men came up behind her and took her.
