The attorney argued that these injuries supported Sheppard's claim that an intruder knocked him unconscious before killing Marilyn Sheppard. The defense attorney also noted that the crime scene was extremely bloody, but police officers found only a small droplet of blood on Sam Sheppard's pants.
Testing the blood for evidence
After Sheppard was not found guilty and released, the police went back to the crime scene to inspect what could've occurred.
Police solving the case
One officer went to the hospital to gathered Sam's clothes, including his waterlogged shoes, belt, boxer shorts, and pants. On the trousers he spotted a large bloodstain on the left knee, suggesting that he had knelt in blood.
Sam Sheppard Convicted for Murder
The blood got tested and linked Sheppard to murdering his wife. In the second half of the case, pursuant to a judge's order, both the bodies of Marilyn Sheppard and Sam Sheppard were exhumed for DNA and forensic analysis.
After being released from the hospital Sam went to police station to get questioned and did not admit to having an affair with Sue Hayes. Then Sue Hayes came and admitted that their relationship did turn sexual.
On August 16, a grand jury met to consider evidence against Sheppard. He told jurors that there was "some evidence" that Sam wanted a divorce, but Marilyn refused to give him one. On August 17, just one day after Sheppard has been released from jail on $50,000 bail, the grand jury returned a first-degree murder indictment against him and he was re-arrested.
