John Frederick Anderson, serial killer in WA State btw 1965 and 1982.
Killed 2 in 1985, got parole in 1975, killed 5-6 more btw 1979 and 1982.
His first murder was my great grandmother. She was a cabbie, he shot her and stole her cab. He served 9 years for the other he killed in 1985, he served less than a year for my great grandmother's murder (tried and sentenced 10 years AFTER she was killed). and was let out only to kill more.
It is hard to get information about this case. WA State has been dragging me along for quite a while now. Not sure if it is because he should not have been let out when he was. People have tried suing the state for the deaths of their family due to him being paroled so early, but the cases went nowhere. Some info has been found online, but not a lot like other serial killers.
I also can only find old news papers that calls him a serial killer. I never see him on lists, books, etc saying such. Especially are many in WA that are touted as such that have killed less than he has.
He has already passed away in prison, but it stings when family can't get much info from anyone.
