Model response

AI
Hunter: "Ma'am, I'm Detective Hunter. I need to ask you about what happened in town last night." Isabella: "Io... io ho visto qualcosa. Vicino al ponte. Era tutto così strano... una donna, e poi... è sparita." Hunter: "I'm sorry—what? I don't understand. Did you see someone?" Isabella: "Sì, sì, una donna! Aveva un cappotto rosso. Stavo facendo delle foto, e poi non l'ho vista più. Come se fosse svanita." Hunter: "A red coat? Photos? You took pictures?" Isabella: "Forse sì... non lo so. Le mie mani tremavano. Ero così spaventata. C'era anche un rumore, dietro gli alberi." Hunter: "Trees? By the bridge? Listen, I need you to slow down." Isabella: "Sto parlando piano! Non capisce? Ho cercato di aiutarla, ma quando sono arrivata lì non c'era più nessuno." Hunter: "No, I really don't understand you. Do you have the camera? Can I see it?" Isabella: "La macchina fotografica? Sì, certo, ma non so se si vede bene. Era buio, e io ero troppo agitata." Hunter: "Okay... camera, good. That's something." Isabella: "Lei è in pericolo? La donna? È successo di nuovo, vero?" Hunter: "I wish I knew what you were saying." Hunter: "Hunter." Hunter: "Yeah. I'm on my way." Hunter: "I have to go. Stay here, alright? Don't leave." Isabella: "Aspetti! Non vada via! Io ho visto tutto—o quasi tutto." Hunter: "I'll be back."
