^ from that article:
Years ago, when she was working as a medical examiner, she said she did hundreds of autopsies. Tangeman asked her about a request from a chief medical officer in Minnesota who told her that if she didn’t stop doing “second opinion” testimony for defense attorneys, she would no longer be asked to perform autopsies in that state. While Dr. Ophoven said Tangeman was “mischaracterizing the event” she did admit that “he asked me to stop doing defense cases in Minnesota, so I did.”

“In your deposition, you said that vaginal birth can cause skull fractures,” Tangeman said to the doctor. “You attributed Kayley’s skull fracture to traumatic vaginal birth?” It was pointed out that Kayley was born by C-section. Dr. Ophoven said that when she said that in error, she also clarified it could have also happened during a C-section. “Dr. Haney said a C-section couldn’t cause this,” Tangeman said. “Yes, it’s unlikely, but it can happen,” Dr. Ophoven said. “In a report you wrote in 2007, regarding a little girl from Washington State who had all sorts of head injuries but no retinal hemorrhaging, you wrote that because there was no retinal hemorrhaging there was no evidence of abuse. But when we do have retinal hemorrhaging, you say it means nothing.” Dr. Ophoven said the logic between the two cases “was not the same.”

The crowd called in a sexual-assault trauma nurse and a medical examiner to testify that Gladue had an 11-cm-long cut, likely caused by a sharp instrument, which would not likely to have been caused by fingers or a fist. The experts said the wound would not have been as clean as it was and there would have been more bruising.
my "mistaken" comment was to point out how laughable it is to assert that this could have been consensual. If the impacts of your sex are so bad that two medical professionals testify that it would have been caused by a sharp object and deliberate force, then chances are it wasn't really "rough sex". You can't legally consent to physical harm of that degree in Canada.
