Model response

AI
Hunter: "Excuse me. You were at the apple festival yesterday, right? I need to ask about what you saw." Isabella: "Sì... sì, ero lì. Ma non voglio parlare di quello che ho visto. È stato terribile." Hunter: "I'm sorry, I don't follow. Did you see someone leave with the missing woman?" Isabella: "Non so... ho visto un uomo vicino ai tavoli, poi lei sembrava spaventata. Dopo... è sparita. Io stavo facendo foto, solo foto." Hunter: "Slow down. You saw a man near the tables and then she disappeared?" Isabella: "Sì, sì! L'uomo aveva una giacca scura... forse blu. E guardava sempre dietro di sé. Mi sento male a pensarci." Hunter: "A dark jacket. Good. Did you get a picture?" Isabella: "La macchina... la mia fotocamera." Hunter: "Your camera. Right. Can you show me?" Isabella: "Aspetti..." Hunter: "Take your time." Isabella: "Qui... ma la foto è sfocata. Sono tremata. E c'era un suono... come un urlo, forse." Hunter: "An outburst, an argument? Was anyone else there with her?" Isabella: "C'era folla... tante persone. Ma io ho visto solo per un momento. Poi ho avuto paura." Hunter: "I appreciate it. Anything else? Any vehicle, any direction he went?" Isabella: "Una macchina scura, credo. Non ho visto bene. Mi dispiace... sono confusa." Hunter: "No, this helps more than you think." Isabella: "Lei sta cercando le persone scomparse, vero? Io... non voglio tornare là da sola." Hunter: "Yeah. I’m on it." Hunter: "Hold on—I've got to take this." Isabella: "Pronto? Cosa succede?" Hunter: "Hunter here. ...Yeah. I’m coming."
