Melanie: *mumbling to herself, looking troubled at her camera* Ach nein... das kann nicht wahr sein... Hunter: Excuse me, miss. I'm Detective Hunter. You were at the apple festival last night, right? Taking photos? Did you see anything unusual—a woman in a red coat, arguing with a tall guy near the cider tent? Melanie: *shaken, eyes wide, speaking rapidly in German* Ich... ich habe sie gesehen! Der Mann... er war groß, dunkle Jacke! Er hat sie gepackt und in den Transporter gezerrt! Es war dunkel, aber ich hab's mit dem Foto... oh Gott! Hunter: *confused frown* Uh... ma'am? English? Do you speak any English? Foto? You took a photo? Of a... transporter? Melanie: *gesturing frantically at her camera, voice trembling* Ja, Foto! Hier! Schauen Sie! Der Van... Nummernschild... blau! Er hat sie hineingezogen, sie hat geschrien! Bitte, helfen Sie! Hunter: *leaning in, puzzled, trying to decipher* Okay, slow down. Van? Blau... blue van? License plate? You saw a woman get pulled in? *pulls out notebook* Can you describe the guy? Tall? Dark jacket? Schreien—scream? Melanie: *nodding vigorously, near tears* Ja, ja! Groß, Bart! Er hat sie festgehalten... am Zelt, Cider-Zelt! Ich hab Angst... Polizei muss kommen! Hunter: *nodding, piecing it together* Alright, beard, tall guy at the cider tent. Got it. This photo—can I see? This could be a break— *phone rings* Hunter: *checking phone* Damn. Excuse me one sec. Hunter here. Yeah? Now? *sighs* On my way. *to Melanie* Stay here, okay? I'll be right back—don't go anywhere! Melanie: *whispering shakily* Beeilen Sie sich... bitte...
