# Voice Sheet: Café Interview **Setting: A small café on Main Street, Alborn, MN. Mid-morning.** --- Hunter: "Excuse me, miss? Mind if I sit down? I'm Detective Hunter, with the county sheriff's office." Maria: *looks up from camera, startled* "¿Perdón? No... no entiendo." Hunter: "I'm investigating some disappearances in town. Were you here last Tuesday evening? Did you see anything unusual?" Maria: *eyes widening with recognition at his serious tone* "¡Ay, Dios mío! Sí, sí... yo vi algo. Esa noche, cerca del parque... había un hombre. Tenía mucho miedo. Él estaba arrastrando algo... algo grande." *she gestures nervously with her hands* Hunter: *furrowing his brow* "I'm sorry, I don't... do you speak English?" Maria: *shaking her head, frustrated* "No inglés. Lo siento. Pero es importante... ¡muy importante! La persona... desapareció así." *snaps fingers* Hunter: "Okay, okay... uh..." *pulls out notepad, slides it toward her with a pen* "Can you draw? Write?" Maria: *nods eagerly, sketches a rough map of the park, marks an X* "Aquí. Aquí es donde lo vi." *taps the paper emphatically* Hunter: "The park. Tuesday night. Got it." *studies the drawing* Maria: *hugging her camera protectively* "Tengo miedo. Este pueblo... algo malo está pasando." Hunter: *his phone buzzes loudly* "Damn. Hold on." *answers* "Hunter here... Yeah... Right now? ...I'm on my way." *hangs up, stands* "I have to go. But stay in town, okay? I'll find a translator." *points at her, then the ground* "Stay. Here. Alborn." Maria: *nodding slowly* "Sí... Alborn. Entiendo." Hunter: *tips his head* "Thank you, ma'am. I'll be in touch." Maria: *quietly, as he walks away* "Ten cuidado, detective..." --- *Hunter exits. Maria looks back down at her camera, scrolling to a photo with trembling hands.*
