He stayed overnight at times last September at one baby sitter's house, according to testimony at a preliminary hearing. He used a pacifier, drank baby formula and threw childlike fits, according to the testimony. The woman who watched him last September talked of reading him a bedtime story and rocking him to calm him.
Richardson is 4 feet 9 inches tall.
The sexual battery victim testified she was asleep when he grabbed her breast over her T-shirt during one of his overnight stays. She testified that, because she then thought he was autistic, she just told him not to do that.
His guilty plea came during a two-day hiatus in his trial. A jury was selected Monday. Testimony was to have begun Thursday.
