Josh Hedrick and Rebecca LeGrand present their final arguments to the jury. They bring in a bed with the actual bloody sheets from the crime scene for a dramatic reenactment. Prosecutor Stephen Crump reiterates his argument that the blood spatter present at the crime scene is not possible unless someone else shot David Leath. Amidst this back-and-forth, we sat down with Stephen Walker, who claims Raynella Leath tried to kill him years ago, a claim Raynella denies. And none of Walker’s claims are allowed in court. Join 48 Hours’ correspondent Erin Moriarty as she revisits the murder investigation of Raynella Leath.
