This confession, along with other contradictory statements Evans made during the police interrogation, has been cited as proof of his guilt. Several authors who have written about the case have argued that the police provided Evans with all the necessary details for him to make a plausible confession, which they may have in turn edited further while transcribing it. Furthermore, the police interrogated Evans over the course of late evening and early morning hours to his physical and emotional detriment, a man already in a highly emotional state. Evans later stated in court that he thought he would be subjected to violence by the police if he did not confess, and this fear along with the shock of discovering that both his wife and daughter had been strangled, likely induced him to make a false confession. The police investigation was marred by a lack of forensic expertise, with significant evidence overlooked.
