In this case, the defendant was ruled to be MR and thus, was not eligible for the death penalty. Reading this decisions gives important insights re: how the courts weigh and judge conflicting expert testimony and evidence re: IQ scores and adaptive behavior. It is interesting to see how the court accepts or does not agree with different expert testimony and how it attends to the two primary professional definitions (AAMR/AAIDD APA) of MR.
Of interest re: IQ scores are discussions of the importance of full scale global IQ scores in the context of sub-composite discrepancies (Verbal vs Performanc IQ) and the relevance of the Flynn Effect. Also of interest is how the subjects history was used to establish MR during his developmental period (before age 18), the third prong of the accepted MR definitions (IQ deficit; adaptive behavior deficit; MR originating before age 18).
