A 22-year-old man is accused of using a sword to stab and kill his father while he was sleeping.

The suspect told officers he had left to buy beer when someone must have killed his father. But he later confessed to doing the deed.

Elias Walker told police he had been staying at the Fort Moultrie Motel for a couple months. Walker told officers he drank six beers but needed more. So he left Room 21 unlocked and set out on a beer run, according to an incident report.

He said he came back later and found his father suffering from stab wounds to his neck and chest and told police that is why he called.

Investigators found no signs of forced entry. But the police said he was unusually calm considering how severe his father was injured. Walker added his father accumulated many enemies at the motel.

But he soon admitted to the killing, and he hung his head during a hearing.
