Mark Day testified as a witness in the civil trial about responding to a disturbance at 360 North Rockingham in 1984 or 1985 while employed by Westec Security, a private residential security firm. He said he was the first person at the scene and encountered Nicole Simpson running across the yard, hysterical, crying, and very upset; he recalled that she said someone had lost his temper and that she was afraid, though he could not provide an exact quotation. At the time of his testimony, Day was an LAPD sergeant assigned to Newton Division and had served with the department for nine years.
