Model response

Melanie: "Entschuldigung... ich kann kaum darüber sprechen. Es war gestern nach dem Apfelfest, und plötzlich war alles so seltsam. Die Leute verschwanden einfach. Ich habe es mit der Kamera gesehen... oder glaube ich zumindest. Alles ist durcheinander." Hunter: "I’m sorry, I didn’t catch any of that. I’m looking into what happened during the festival. Did you see someone leave with the missing person?" Melanie: "Ich habe eine Frau gesehen... oder einen Schatten? Nein, nein, ich weiß es nicht. Ich war zu aufgeregt. Es war dunkel, und dann hörte ich nur dieses seltsame Geräusch." Hunter: "Slow down. You’re shaken up, I get that, but I need something useful. Was it a man? A truck? Anything?" Melanie: "Ich verstehe Sie nicht... ich spreche kein Englisch. Bitte... mein Kopf ist ganz wirr." Hunter: "Right. Of course. This is getting me nowhere." Hunter: "Hold on—my phone. Detective Hunter." Hunter: "Yeah. I’m on my way."
