Model response

AI
Hunter: "Maria? I’m Detective Hunter. I heard you were at the café when Lila Peterson disappeared." Maria: "¿Desapareció? No… no, no puede ser." Hunter: "I’m sorry. I don’t speak Spanish. Did you see Lila?" Maria: "La vi ayer por la tarde. Estaba junto al puente, cerca del huerto de manzanos." Hunter: "The bridge? Orchard? Maria, slow down." Maria: "Tenía miedo. Miraba hacia el bosque, como si alguien la estuviera siguiendo." Hunter: "Someone was following her?" Maria: "No lo sé. Yo estaba tomando fotografías del río. Entonces escuché un ruido… un golpe. Cuando miré otra vez, ella ya no estaba." Hunter: "You took photographs?" Maria: "Sí. Quizá… quizá mi cámara vio algo que yo no vi." Hunter: "Your camera may have caught something. Can you show me the pictures?" Maria: "Sí, pero… tengo miedo. En una de las fotos hay una persona entre los árboles. No puedo ver su cara." Hunter: "All right. Don’t delete anything. I need to look at every photo you took yesterday." Maria: "¿Usted puede ayudarla?" Hunter: "That’s what I’m here for. I’ll find someone who can translate—" Hunter: "Hunter." Hunter: "What? … Where?" Hunter: "I’m on my way." Hunter: "Maria, I have to go. Keep that camera with you. Don’t let anyone else touch it, and don’t go anywhere alone." Maria: "¿Qué ha pasado?" Hunter: "I’ll be back. Stay here, understand? Stay in the café." Maria: "Sí… sí. Aquí." Hunter: "Good. I’ll be back as soon as I can."
