Key legal question
Whether the 10.5-year prison sentence was unlawfully excessive despite diminished responsibility
Extracted holding
The appellate court properly assessed the reduced culpability and remained within its broad discretion; the sentence was not unlawful.
Extracted reasoning
The court first estimated the hypothetical sentence without diminished responsibility, then reduced culpability according to the expert findings, and finally accounted for offender-related factors. Its weighting of the expert conclusions and the aggregation of the various offenses was not arbitrary or legally incorrect.
