The jury instruction on mental retardation was not inconsistent and was not
harmful to the defendant in his trial for capital murder. The jury instruction appropriately tracked the definitions of mental
retardation provided by the American Association on Mental Retardation and in
Briseno. Extensive testimony was presented by former teachers,
employers and psychiatrists and the parties' closing jury arguments made clear
that the issue was litigated before the jury.
