Model response

AI
Isabella: *looking troubled at her camera, murmuring to herself* Dio mio... cosa ho visto... Hunter: Excuse me, miss. Sorry to bother you. I'm Detective Hunter with the Alborn PD. Were you at the apple festival last night? Mind if I ask what you saw? Isabella: *shaken, eyes wide, speaking rapidly in Italian* Sì, sì ero lì! Con la mia macchina fotografica... ho visto un uomo! Alto, con un cappotto nero... inseguiva una ragazza verso il bosco! Poi... puff! È sparita! Hunter: *confused frown* Uh... festival? You saw a man? Chasing someone? Do you speak any English? I'm investigating a disappearance—did you witness something? Isabella: *gesturing frantically at her camera, voice trembling* No, no capisco! Guardate le foto! Qui, guardate! La ragazza... capelli rossi... e lui la afferrava! Era orribile! Devo dirlo alla polizia! Hunter: *leaning in, puzzled, trying to follow* Photos? Red hair? Okay, slow down—show me the camera? This could be important. The missing girl from the festival—did you get a picture of her? Isabella: *nodding vigorously, shoving camera toward him, upset* Sì! Ecco! Vedete? L'uomo... occhi cattivi... e la urlava aiuto! Poi luci spente... e niente più. Ho tanta paura! Aiuto! Hunter: *squinting at camera, nodding slowly* Alright, that's... something. Hold on, don't go anywhere. Let me— *phone rings* Hunter: *checking phone* Damn. I gotta take this. Stay here—one minute. *stands, answers* Hunter. Yeah? Another one? Where? ... On my way. *to Isabella* We'll finish this—don't leave town! Isabella: *calling after him, shaken* Aspetta! Detective! Per favore!
