 Next to the pool were dragging marks, and crossing over them and the blood, there were tire tracks made by a small vehicle with a tire model that went out of production in 1993.Because the dragging marks continued over severely inclined terrain that would have made it difficult for one person to drag a body alone, it was believed that the body was dragged by at least two people, then left in a less exposed area of the vacant lot before the vehicle was brought in to transport the body to another location.
