The boy, who is not being named due to his age, was charged Wednesday in juvenile court with first degree rape and child rape.
Police say a teary eyed and soft spoken girl walked into a Kent Red Lion last Thursday afternoon wearing only a shirt and socks. The girl told hotel employees she had just been raped in the woods behind the hotel, according to charging documents.
Police say the girl's face was swollen and she had scratches and welts on her arms and legs.
The girl told officers a boy that she had seen a couple of times with her older brother came to her house earlier that afternoon and said he had a surprise for her. She didn't know the boy's name, but because she had seen him with her brother she trusted him.
She said she walked with the boy toward a nearby gas station and then into a wooded area behind the Red Lion, where he beat and raped her.
Asked by police where the boy hurt her, the girl pointed to her head and then her groin, according to court documents.
Using the information they'd gleaned from the girl, police were able to track down the suspected rapist within an hour.
The boy originally told police he and the girl went to a grocery story and then returned home. When officers told him they had DNA evidence and surveillance video of the crime, the boy changed his story and said the girl asked him to have sex with her, according to court documents.
Police asked the boy if he thought it was improper to have sex with an 8-year-old, to which he relied, "I thought she was older than that," according to police.
The boy, who stands 6-feet tall and weighs roughly 230 pounds, later admitted to police that he hit the girl in the face at least twice. The girl is 4-feet tall and weighs 90 pounds, according to police.
Prosecutors plan to ask the court to schedule a decline hearing, where a judge will decide whether the boy should be prosecuted in adult or juvenile court.
