Whether A.________ committed failure to render aid under Art. 128 CP
The conviction could not be upheld on the existing findings because the record did not sufficiently establish whether any assistance omitted by A.________ was objectively necessary or at least useful before the victim's death.
Art. 128 CP is a pure omission offence of abstract endangerment; success of the omitted aid is irrelevant, but liability still requires that the aid be needed or at least useful. The cantonal findings did not clarify the precise timing of death, arrival of rescue services, or possible immediate help from third parties, so it remained open whether an intervention by A.________ could still have had utility.
