Kris Barbrich, of the SF Medical Examiner’s office, advised me to keep going up the chain of command if I wasn’t satisfied with the response I was getting from the cold case unit. I was tempted. A problem arose when I wasn’t getting the result that I had become attached to — charging the perpetrator. At some point I equated being told that the SFPD wasn’t going to charge said suspect with not being satisfied with their response.
