Kernrechtsfrage
Whether the defendant's deception amounted to arglist under Art. 146 StGB.
Extrahierter Entscheid
Yes. The lies formed a deceptive pattern exploiting the victim's trust and vulnerability; the victim's failure to verify did not amount to sufficient self-responsibility.
Extrahierte Begründung
Simple lies can constitute arglist when verification is difficult or unreasonable, or when the offender prevents verification or exploits a special trust relationship. Here the defendant used a targeted, intensive deception against a trusting, altruistic and vulnerable victim.
