The other man living in the trailer, whose name has not been disclosed, was initially held for questioning but released. That man, age 53, was in a romantic relationship with Jackson, said Scardina. A motive for the killing has not been clearly established, Scardina said.
Sheriff's officials visited the trailer in July for a report of a domestic disturbance, Scardina said. That visit led to one person being placed under a psychological hold, he said.
