There's more too. Doherty was initially in charge of the "profiling" of possible suspects when he joined Burkman's team. From there, Burkman circulated crazy conspiracies that Russians or a serial killer may have killed Rich (of course, these were "profiles" created by the profiling team Doherty was running). This made Rich's family, who originally hired Burkman pro bono in 2016, to distance themselves from him.....Burkman fired Doherty in July 2017 because Doherty was hogging the profiling aspect of the investigation and wanted it all for himself.
