Hunter: "Mind if I sit? I'm Detective Hunter. I need to ask you about last night near the apple festival grounds." Isabella: "Mi scusi... io... non parlo inglese." Hunter: "Do you speak English? Name?" Isabella: "Mi chiamo Isabella." Hunter: "Isabella. Okay. You were taking photos? Camera. Photos." Isabella: "Sì, foto. Sempre foto. Ieri sera... festival delle mele." Hunter: "Last night. Festival. Did you see anything unusual?" Isabella: "Ho visto... qualcosa. Mi tremano le mani ancora." Hunter: "It's okay. Can I see your camera? Show me." Isabella: "Sì, sì. Guarda. Qui... vedi? C'è un furgone blu vicino al capannone." Hunter: "Blue van. Cider barn? Orchard?" Isabella: "Entrata nord, oltre il ponte. Lì. Una ragazza... penso... con uno zaino rosso." Hunter: "Red backpack?" Isabella: "Sì, rosso. Molto rosso. Poi... buio. Ho sentito un urlo. Forte." Hunter: "A scream. What time? When?" Isabella: "Mezzanotte, più o meno. Dodici meno dieci? Non sono sicura." Hunter: "Okay. Faces? Did you see a face?" Isabella: "Ombre. Una mano sul braccio della ragazza. Una giacca... forse verde. Odore di benzina." Hunter: "Green jacket. Gasoline. License plate? Numbers?" Isabella: "Niente targa davanti. Dietro non so. Ho provato a scattare, ma... sfocate." Hunter: "You took photos. Good. More? Scroll. That—stop. Is that the van turning?" Isabella: "Sì. Qui. Vedi? Luci. Poi... basta. Ho avuto paura." Hunter: "Did anyone see you?" Isabella: "Forse sì. Uno mi ha guardata. Occhi chiari. Ho corso via. Sono venuta qui." Hunter: "Are you hurt?" Isabella: "No... solo paura. Non dormo da ieri." Hunter: "I need those photos. Can you bring the camera to the police station? Police." Isabella: "Polizia? Sì. Ma... la scheda... sembra corrotta. Alcuni scatti sono spariti." Hunter: "Corrupted. Missing photos. Don't delete anything. Do not delete." Isabella: "Non cancello nulla. Promesso." Hunter: "Don't go back there. Stay in town. Here is fine." Isabella: "Va bene. Resto qui. Aspetto." Hunter: "One more—north entrance, by the bridge. Any other cars?" Isabella: "Un pick-up scuro, credo. Rumore forte. Poi silenzio." Hunter: "Got it." Hunter: "Excuse me—" Hunter: "Hunter. Yeah. I'm close. On my way." Hunter: "I have to go. I'll be back soon. Keep your camera with you. If someone bothers you, call nine-one-one. Police." Isabella: "Capisco... polizia, sì. Nove-uno-uno." Hunter: "Thank you, Isabella."
