Chase Darkness With Me by Billy Jensen

I think everyone is somewhat fascinated by true crime but they don't want to admit it. This is the first time I have read a true crime book where the author not only describes how they have solved criminal cases but how you can become a crime solver as well. Billy Jensen goes into some of the most maddening unsolved cases he has worked on, in particular, The Golden State Killer that his friend and co-crime solver Michelle McNamara began and he finished with her husband after her sudden passing. He is very open about his obsession and the success he has found utilizing social media. He also shares insight as to his upbringing and how this put him on the path to solving the unsolvable. The stories are fascinating, his methods are unusual and his determination for justice is admirable.
In choosing to only fight to find the killers in cases where the police have given up because of lack of leads or for not being high profile, Billy Jensen has become his own version of Batman and he is urging all of us to be his Boy Wonder.
