AI
Hunter: Ma'am, I'm Detective Hunter with the Alborn PD. I'm investigating the disappearances. Can you tell me what you saw or heard around town recently? Maria: Estoy muy nerviosa. En Alborn han desaparecido varias personas y nadie sabe por qué. Hunter: I don't speak Spanish. Can you tell me in English, or get someone who can translate? Maria: Lo siento. No hablo inglés. Hunter: If you can't speak English, maybe you could point me to someone who can translate. Maria: Mi cámara está siempre conmigo; tomé algunas fotos esta mañana. También puedo llamar a mi amigo Pablo, que es fotógrafo y puede traducir. Hunter: Where is Pablo now? Maria: Está en la biblioteca, preparando una exposición. Le puedo llamar. Hunter: Show me the photos you took. Maria: Claro. Aquí están. En la última toma se ve una sombra cerca de la plaza. Hunter: A shadow near the plaza? What time did you take that photo? Maria: Anoche, entre las 9 y las 10. Hunter: I have to take this call.
