Model response

AI
Melanie: *sits at the cafe table, staring intently at her camera screen, murmuring to herself softly* Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I sit? I understand you're Melanie, the student from Germany? Were you at the apple festival last night when Mrs. Hargrove went missing? Melanie: *looks up startled, eyes wide and troubled, voice shaky* Ja... ich war dort. Ich habe etwas gesehen. Zwei Männer... sie stritten sich. Einer zerrte den anderen in den Wald. Es war dunkel, und ich... ich habe Angst. Bitte, es war furchtbar! Hunter: Uh... ma'am? Sorry, I don't speak German. Do you understand English at all? English? Festival? Missing woman? Melanie: *shakes head vigorously, gesturing wildly with her hands, voice rising in panic* Nein, nein Englisch! Polizei! Gefahr! Der Mann... schwarzer Mantel, groß... er hat sie mitgenommen! Ich habe fotografiert, aber zu dunkel... Hunter: Okay, slow down. *mimes taking a photo* Camera? You took pictures? *points to her camera* Can I see? Missing... poof? *gestures disappearance* In the woods? Melanie: *nods frantically, tears welling up, pushes camera toward him but speaks rapidly* Ja, Wald! Apple festival... Äpfel überall. Ich folgte ihnen ein bisschen, aber dann... weg! Rufen Sie Hilfe! Jemand muss kommen! Hunter: Woods, yeah? Black coat? Tall guy? *tries to repeat her gestures* This is important. Nod if yes—did you see Mrs. Hargrove? The lady with the red scarf? Melanie: *nods, then shakes head confused, clutching her camera* Mrs. Hargrove? Ich kenne nicht Namen. Aber die Frau... schrie. Rot Schal? Ja! Bitte, glauben Sie mir. Ich lüge nicht! Hunter: Alright, red scarf lady. Got it. We need to get this translated—*phone buzzes loudly* Hold on. *checks phone* Damn. I gotta take this. It's the station. *stands* Don't leave town, okay? I'll get someone who speaks German. Here's my card. *hands her card* Melanie: *stares at card blankly, whispers shakily* Danke... bitte schnell... Hunter: Yeah, quick as I can. Stay safe. *hurries off, answering phone* Hunter here—what've you got?
