Hunter: "Excuse me—are you Melanie? I'm Detective Hunter. Did you see anything about what happened last night at the festival?" Melanie: "Ja... ich bin Melanie. Was ist passiert? Wovon sprechen Sie? Ich... ich war dort." Hunter: "I'm sorry, I don't understand German. Do you speak English?" Melanie: "Nein. Ich spreche kein Englisch. Bitte—ich habe etwas gesehen. Ich habe Fotos." Hunter: "Photos? You have photos? Can I see them?" Melanie: "Hier. Ich war nach dem Feuerwerk im Wald. Es war dunkel. Ich habe eine Jacke gefunden. Und... es war Blut. Jemand—sie ist verschwunden." Hunter: "You found a jacket... blood... someone missing? Who's missing? Did you tell anyone?" Melanie: "Ich habe niemandem gesagt. Ich hatte Angst. Ich wollte zur Polizei, aber... ich wusste nicht, wie. Bitte, glauben Sie mir, ich habe Bilder." Hunter: "Okay. Slow down. Where exactly did you find it? When?" Melanie: "Hinter der Schule, am Marshweg. Gegen zehn Uhr abends. Die Bilder—siehe hier. Man kann Spuren im Schlamm sehen." Hunter: "Marshweg behind the school, ten p.m... I need to see those pictures properly. Can I—" Melanie: "Ja, sehen. Bitte. Es ist wichtig. Bitte helfen Sie—" Hunter: "Hold on—I've got to take this call. Stay right here, okay? Don't leave."
