What are some possible items of corroboration in a sexual assault case?

In the instant case the trial Judge reviewed as possible items of corroboration such evidence as a tear and a semen stain on the complainant’s panties; some bruises observed on the person of the complainant; dirt on the back of her clothing; and her dishevelled appearance. Initially he properly told the jury that they could not consider any of these items as corroboration as they failed to meet the requirements set out in Rex v. Baskerville, supra. His actual words were: “It’s dependent on her own testimony, and it doesn’t show the accused did it either.”
