Maria: "¿Usted... usted es policía? Vi algo en el festival de la manzana. No fue normal. Había una mujer llorando, y luego... desapareció. Yo tomé fotos, pero ahora tengo miedo." Hunter: "I’m Detective Hunter. Slow down. I need to know what you saw at the festival." Maria: "No entiendo... inglés... no. La plaza, las luces, la gente... y después el coche oscuro. Yo estaba fotografiando el lago. Then I heard—gritos. Mucho miedo." Hunter: "Dark car? A woman screaming? Maria, I need names. Did you see who she was with?" Maria: "No sé nombres. Solo... un hombre alto, sombrero negro. Él miró a mi cámara. Me vio. Me vio de verdad." Hunter: "Okay. Tall man, black hat. That’s something. Did he take her? Did she leave on her own?" Maria: "No, no... ella no quería ir. Tenía la cara pálida, así, muy asustada. Después... el hombre la empujó. Yo quería ayudar, pero..." Hunter: "But what? Maria, this is important." Maria: "Yo estaba sola. Y mi cámara... grabbed this." Hunter: "You have photos?" Maria: "Sí. Aquí. Mire... there. La sombra. El coche." Hunter: "Hmm. This is blurry, but it helps. Was that before or after the lights went out?" Maria: "Después. When the music stopped. Everyone estaba mirando los árboles. Yo pensé que era una broma del festival, pero no." Hunter: "No joke. We’ve had more than one disappearance, and I need every detail you can give me." Maria: "¿Desapariciones? Dios mío... entonces no fue solo una mujer." Hunter: "No. It may not be. Have you seen anything else—anyone following you since then?" Maria: "Sí... maybe. An old truck near the café. Same man? No sé. Yo no dormí bien anoche." Hunter: "All right. Stay where I can reach you. Don’t go back to the festival grounds alone." Maria: "Yo no quiero volver. There was something wrong there. Muy wrong." Hunter: "That’s enough for now. I’m getting a call—" Maria: "¿Señor? Wait—" Hunter: "Hunter speaking." Maria: "Please... no me deje sola." Hunter: "I’m not leaving you alone. I have to take this, but I’ll be back."
