Transgender female Twitter engineer, 32, is charged with raping her estranged wife the day after serving her with divorce papers (McCallum has been listed as one of the top ten most important LGBT people in tech and she has spoken at length about her transition after being born biologically male.) She and her wife, who has not been named due to the nature of the crime, had been married for more than six years. The San Francisco Examiner reports that the 32-year-old engineer and her wife were separated but were still having sexual relations by the time of the alleged crime. McCallum had served her wife with divorce papers on January 25 but they met up at some point that evening. At 2am on January 26, police responded to a sex assault call at a residence in the Mission district of San Francisco. McCallum's wife accused her of rape, but McCallum has denied any wrongdoing. According to the San Francisco police, the state of California classifies rape as penial on vaginal assault. They were not able to reveal any of the specific details about the suspect or the victim, but said that in order for a rape to have occurred, it would have to meet the aforementioned criteria.
