i have watched so many true crime documentaries and this case was the easiest to guess. The murderer literally left so many clues incld the fact that he had been arrested before. The murderer although uneducated but was able to outsmart the police? This wasnt the 'most toughest case' it was simply a case the police were lazy to follow through the clues. The character portrayal of the murderer was also not described properly. Childhood neglect, attacked and stabbed for no reason, falsely arrested him and his wife, tortured by the police- all of this impacted him deeply where he thought everyone is out to get him in someway which led to him killing people who upset him as well as by doing so making a point that how bad the police are at their job.
