Forty-four-year-old Michael Kenneth Peterson was picked up late Monday afternoon and charged with murder.
Richland County Coroner Gary Watts says the victim was 54-year-old Brenda Witherspoon. The cause of death has not been released.
Police had been called to the home by a relative about noon Monday.
Investigators think Peterson and Witherspoon lived together.
No one else was in the home.
It wasn’t clear Tuesday if Peterson has a lawyer.
