The police are called to the scene and investigate. They discover a trail of blood leading from the mansion to the nearby woods. The body of Gilbranson is found in the woods, with no signs of struggle or violence. The police believe that someone must have killed Gilbranson and then disposed of the body to avoid suspicion.
