The teenager who prosecutors say was raped by Joshua L. Smith on Sept. 6, 2006, has a congenital syndrome that causes deformities in her bones, skin and hair, and mental and developmental disabilities.
She was 17 at the time of the attack but had the cognitive abilities of a 12-year-old.
She is 19 now and, although she mixed up the names of some body parts during her testimony Thursday, she clearly told the jury in Smith's rape trial that he forced her to have sex in the basement of his St. Paul home.
Smith, 18, is on trial in Ramsey County District Court on two counts of first-degree criminal sexual conduct. He is accused of the September 2006 rape and the rape of another woman shortly after midnight New Year's Day 2007.
That 57-year-old victim testified Tuesday that she was brutally and repeatedly raped, kicked and beaten in the parking lot of the Salvation Army on Payne Avenue. Smith was 16 at the time of the attacks and was certified to stand trial as an adult.
The teenage victim said Thursday that she had known Smith since she was in seventh grade.
"Were you friends?" prosecutor Jill Fedje asked.
"Not really," the teen said.
