I believe he is just one of at least many suspected serial killers (https://en.wikipedia.org/wiki/List_of_serial_killers_active_in_the_2020s) but not news worthy until caught.
The only thing newsworthy about such deaths is if they were committed with an A-s-s-ault Rifle and mass murder. Stealth murders are not interesting.
I always think of Juan Corona of Yuba City...
