Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions about last night's incident at the apple festival? You were taking photos, right? Maria: ¡Ay, Dios mío! Sí... vi algo horrible... Un hombre arrastrando un saco grande por el callejón oscuro. ¡Parecía que había alguien dentro, luchando! Hunter: Uh... sorry? I don't speak Spanish. Do you understand any English at all? Maria: ¿Qué? No... no hablo inglés. ¡Por favor, escuche! Era cerca de la carpa de las manzanas... la medianoche... ¡desapareció alguien! Hunter: Okay, slow down. Camera? (points to her camera) Fotos? You saw something bad? Maria: ¡Sí, fotos! Mira... (shows camera screen, voice shaking) Aquí, borroso, pero ese hombre... capa negra, alto... ¡lo seguí un poco, tenía miedo! Hunter: Blurry guy in a coat? Alto? Like tall? Can you describe him more? Wait, what about the bag—saco? Maria: ¡Saco grande, pesado! Se movía... como si gritara dentro. Corrí... llamé a la policía, pero nadie vino rápido. ¡Otro desaparecido! Hunter: Damn, that's... (phone buzzes) Hold on, this could be related. Excuse me one sec. Hunter: (on phone) Hunter here. Yeah? Now? Alright, on my way. Hunter: Sorry, miss, duty calls. Stay here—I'll get an interpreter back ASAP. Don't delete those photos! Maria: ¡Esperen! ¡Vuelva, por favor! Es importante...
