The original entails cops coming into the house the next day and shooting and killing Katie. The alternate ending features Katie gruesomely slitting her throat, and the theatrical ending is what most people saw in the theaters when Katie supposedly kills Micah and becomes possessed by the demon. According to Entertainment Weekly, there was also an ending they never filmed: “A possessed Katie corners Micah and bludgeons him with his precious camera, while viewers watch from the camera’s POV.” psychic oracle chat http://www.psychicoraclechat.com
