Although the coroner's post-mortem examination had found that Warmbier's teeth were "natural and in good repair", two of Warmbier's private dentists testified that his post-mortem dental x-rays indicated that some of his lower teeth were bent backward when compared to his earlier dental records, consistent with "some sort of impact". A scar on Warmbier's foot, previously described by the coroner as "inexplicable", was held up by some expert witnesses as evidence that Warmbier may have been subjected to torture (such as electric shock) by his North Korean jailers.
