# Voice Sheet: Café Encounter **Setting: A small café on Main Street, Alborn, MN. Late morning.** --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Maria: *looks up from camera, uncertain* "¿Perdón? No... no entiendo." Hunter: "I'm Detective Hunter. I'm investigating some disappearances in town. Were you at the apple festival grounds yesterday evening?" Maria: *eyes widening, visibly shaken* "¿Las desapariciones? Sí, sí, yo estuve allí. Vi algo... algo terrible. Había un hombre cerca del granero, y una mujer gritó, y luego... nada. Silencio. Tengo mucho miedo." Hunter: *frowning, leaning back* "I'm sorry, I don't... Do you speak English?" Maria: *shaking her head, frustrated* "No hablo inglés. Lo siento. Pero necesito que entienda—vi algo malo. Muy malo." *taps her camera urgently* "Fotos. Tengo fotos." Hunter: "Photos? You took photos?" Maria: *nodding vigorously* "Sí, sí. Fotos." *scrolls through camera, hands trembling* Hunter: "Can I see those? May I?" *gestures toward the camera* Maria: *hesitates, then turns the screen toward him* "Mire. El hombre... aquí, cerca de los árboles." Hunter: *squinting at the screen* "That's... that's near where the Johnson girl went missing. I need to—" *Hunter's phone rings* Hunter: *answering* "Hunter here. ...What? When? I'm on my way." *stands abruptly* "I have to go. Don't leave town, okay? Stay. Here." *gestures at the ground* Maria: *confused, anxious* "¿Qué? ¿Qué pasa? ¡Espere, por favor!" Hunter: *already moving toward the door* "I'll find someone who speaks Spanish. Stay put!" Maria: *quietly, watching him leave* "¿Qué está pasando en este pueblo?" --- **End Scene**
