Melanie: "Es war schrecklich. Ich habe versucht, Fotos von der Landschaft zu machen, aber dann... sah ich sie. Zwei Männer in einem dunklen Lieferwagen. Und dann war da dieser Schrei." Hunter: "Excuse me, miss. I'm Detective Hunter. I'm investigating some strange activity around town. Did you happen to be near the old mill yesterday evening?" Melanie: "Die alte Mühle? Ja, dort war ich. Ich verstehe kaum etwas... Bitte, schauen Sie auf meine Kamera. Ich habe alles gesehen." Hunter: "Whoa, slow down. I... I don't speak German. Do you know any English? Just... yes or no?" Melanie: "Nein. Kein Englisch. Aber hier—" *she turns the camera toward him, her hands trembling* "—das Foto. Der Mann mit dem Messer. Er hat jemanden in den Wagen gezerrt." Hunter: "Let me see that... A knife? This is a picture of a man with a knife. And a van. You saw this happen? You witnessed an abduction?" Melanie: *nodding, tearful* "Ja, ja! Ich habe mich hinter einem Baum versteckt. Sie sind in Richtung Wald gefahren. Ich hatte solche Angst, Hilfe zu holen." Hunter: "The woods... south of here, right?" *she points emphatically south* "South. Okay. This is big. Can I keep this camera for evidence? Camera—evidence?" *he points to the camera, then his badge* Melanie: "Ja, nehmen Sie es. Bitte finden Sie sie." Hunter: "Thank you. Danke—that's all I know. We'll get them." *his phone buzzes* "Detective Hunter... Yeah... Right now? I'm just around the corner. On my way." *he clips the phone to his belt* "I have to go. Someone spotted the van. Stay right here, someone will come take your statement. Okay? Stay." *he gestures for her to remain seated* Melanie: "Passen Sie auf sich auf, Detective." Hunter: *already walking away* "I will. Just... stay put."
