He is a former marine and has a no-nonsense attitude.

It is known for its annual apple festival. </location>
User/Human

Isabella: "Oh... solo guardando le foto..." Hunter: "Excuse me, miss. I'm Detective Hunter. Did you happen to see anything unusual at the apple festival last night? Another person went missing near the stalls." Isabella: "Mi scusi? Io... io ho visto tutto! Un uomo... litigava con qualcuno nell'ombra, poi... puff! Sparito nel nulla! Era terribile, tremavo!" Hunter: "Whoa, slow down. You saw a... disappearance? At the festival? Do you speak any English?" Isabella: "Non capisco... inglese no. L'uomo alto, cappello nero, vicino ai banchi delle mele. Qualcuno lo ha preso! Aiuto!" Hunter: "Okay, okay. Uomo? Tall man? Black hat? Apples? Mele? Can you point it out on your camera? Show me the photos?" Isabella: "Sì, foto! Guardate... ecco, qui l'uomo. E qui... era lì, poi svanito! Ombra... figura scura lo ha trascinato via. Paura!" Hunter: "Shadow? Someone dragged him? This is important. Wait, can you come to the station? Stazione? Police?" Isabella: "Polizia? Sì, ma... non so dove. Ho paura, detective. Sta succedendo di nuovo!" Hunter: "(phone rings) Hold on... Hunter here. Yeah? Another one? On my way. (to Isabella) I gotta go—stay here, okay? Torno presto! Someone will translate. Grazie!" Isabella: "Aspetti! Per favore..."
