Model response

AI
Hunter: "Pardon me, ma'am. I'm Detective Hunter. Could I ask you a few questions about the recent disappearance in Alborn?" Maria: "¡Dios mío, no entiendo inglés! Estoy muy nerviosa y sacudida por lo que vi en mi cámara ayer." Hunter: "Sorry, I don't speak Spanish. Do you have any information on the event?" Maria: "Las fotos muestran una sombra extraña cerca del festival de manzanas. ¡Tengo mucho miedo de lo que significa!" Hunter: "I can't understand a word. This is not helpful. Can you show me the pictures?" Maria: "Por favor, alguien que ayude. Vi algo que podría explicar las desapariciones misteriosas y me ha dejado temblando." Hunter: "My phone is ringing. I need to take this call from the station. Excuse me."
