She said she lost consciousness and woke up in a pool of blood.Investigators say after some time, Southerland called for medical assistance. Deputies say he originally didn't admit to harming her, but said medication he takes causes him to black out.According to doctors, the victim's injuries weren't consistent with a fall, but rather abuse.
