Melanie: *looking troubled, speaking rapidly in German with a shaky voice* Ich... ich habe es gesehen. Gestern Abend am See... ein Mann, er hat jemanden in den Wald gezogen. Es war dunkel, aber ich habe Fotos gemacht. Oh Gott, er hat mich fast entdeckt! Hunter: Excuse me, miss? I’m Detective Hunter with the Alborn PD. I couldn’t help but notice you seem upset. Did you see something related to the recent disappearance at the lake? The one with the hiker? Melanie: *eyes widening, gesturing frantically at her camera, still in German* Die Kamera! Schauen Sie, die Bilder... es war kein Unfall. Der Mann trug eine Maske, und das Opfer hat geschrien. Bitte, Sie müssen mir glauben! Ich bin Melanie, aus Deutschland... ich verstehe nicht... Hunter: Uh... German? Okay, hold on. Do you speak any English? *pauses, looking puzzled and leaning in closer* Photos? You took photos of... what, exactly? This about the lake incident last night? Melanie: *shaking her head, pointing to the camera screen, voice trembling* Nein, nein Englisch. Aber hier... sehen Sie? Der Wald, die Schatten... es war gruselig. Die Polizei muss kommen! Jemand verschwindet, genau wie die anderen! Hunter: Alright, slow down. *tries to mimic a camera gesture, frustration creeping in* Pictures? Show me? *glances at her camera but can't understand the images without context* Look, if you witnessed something suspicious, I need details. Name? Contact? Melanie: *nods vigorously, fumbling with her phone to show a translation app, but speaks first in German* Hunter? Detective? Ich heiße Melanie. Studium hier. Aber es ist gefährlich... der Mann, er kommt zurück! Hunter: Melanie, got it. *nods, pulling out a notepad, speaking slowly as if that helps* Okay, Melanie. Dangerous man? At the lake? *his phone buzzes suddenly* Damn it—hold that thought. *answers the call* Hunter here. Yeah? Now? *stands up abruptly* I gotta go—stay here, I'll be right back with someone who speaks German. Don't move! Melanie: *watching him leave, murmuring anxiously in German* Warte... bitte, geh nicht...
