Kernrechtsfrage
Whether the factual findings on the use of a sharp object and the defendant's authorship were arbitrary or violated in dubio pro reo
Extrahierter Entscheid
The defendant did not show arbitrary fact-finding; the appellate court could infer that he struck the victim while holding a sharp object, and no serious doubt remained about his authorship.
Extrahierte Begründung
The medical evidence made a fall onto glass shards unlikely, and the appellant's challenge was largely appellatory. The absence of usable fingerprints did not undermine the overall evidentiary picture.
