Police think Tabak watched sex videos before killing Yeates. One of Tabak's favourite films - "Sex and Submission" - was set in a dungeon. When police searched his computer hard-drive, they found three images of a woman who looked like Joanna Yeates. In recent times he had moved from browsing violent fantasies online to paying prostitutes for services in trips to Newcastle and LA. The judge ruled that such details were inadmissible as evidence, so the jury weren't told about these during the trial.
