Key legal question
Whether the appellate court's findings on the violence background and force of the stabs were arbitrary or violated in dubio pro reo.
Extracted holding
No. The court's assessment that the defendant used a knife with some force and that prior violence was relevant was sustainable.
Extracted reasoning
The knife penetrated clothing and deep enough to injure the arm artery; the court could infer some force. The history of abuse was acknowledged and not ignored, but the alleged lung injury by assaults was not proven.
