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

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

Maria: *looking troubled, fiddling with her camera, speaks in rapid, shaken Spanish* ¡Dios mío, fue terrible! Vi algo anoche en el festival de manzanas... una sombra, y luego la chica desapareció. ¡No sé qué hacer! La policía no me entiende... Hunter: Excuse me, miss? I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions about the incident at the apple festival last night? Did you see anything unusual? Maria: *eyes widening, gesturing frantically with her hands, still in Spanish, voice trembling* ¿Usted es policía? ¡Por favor, escúcheme! Estaba tomando fotos cerca del puesto de sidra, y vi a esa mujer joven discutiendo con alguien. Luego... ¡puf! Se fue. Como los otros. ¿Qué está pasando en este pueblo? Hunter: Uh... I'm sorry, what? I don't... Do you speak English? Festival? You saw something? *pulls out a notepad, looking increasingly puzzled, glancing around the quaint cafe with its checkered tablecloths and scent of fresh coffee* Maria: *shaking her head, pointing to her camera and mimicking a disappearance with her hands, voice rising in frustration* No, no inglés. ¡Mira las fotos! *fumbles to show him a blurry image on her camera screen of festival lights and a crowd* Aquí, mira... la sombra. Alguien la llevó. ¡Tengo miedo! Hunter: Photos? Okay, let's see... *leans in, squinting at the screen, rubbing his jaw* That looks like the cider stand. Shadow? You mean a person? Miss, this is important. Can you describe it? Tall? Short? *mimes heights, trying to bridge the gap, his no-nonsense expression cracking with confusion* Maria: *nods vigorously, pointing at the photo again, mixing gestures with words* ¡Sí, alto! Hombre con sombrero, creo. La tomó del brazo y se fueron hacia los árboles. Como fantasmas. ¿Por qué nadie ayuda? *clutches her camera closer, glancing nervously at the quiet street outside the cafe* Hunter: A man in a hat? Grabbed her arm? Towards the trees? *nods slowly, jotting notes, piecing it together despite the language barrier* Alright, that's helpful. If you could come down to the station later, we could— *Hunter's phone buzzes loudly in his pocket. He checks it, face hardening.* Hunter: Hold that thought—one second. *answers the call* Hunter here. Yeah? Another one? Damn it. On my way. *hangs up, stands abruptly* Sorry, miss. Duty calls. Stay safe, and if you remember more, find someone who speaks Spanish at the station. *gives a curt nod and strides out toward his unmarked car parked by the apple orchard sign*
