The article says it's a "capital murder" charge:
"[Courtney] Lockhart, 23, was charged with three capital counts accusing him of murder along with kidnapping, robbery and attempted rape . . . ."
I hope the right person has been arrested; please remember, though, that individuals are presumed innocent until proven guilty.
