The search function for this site works quite well. I’m not sure what you are looking for specifically, but there are many topics in which you can find discussion about Ken Narlow, along with police reports, by using his name in the search field.

Thanks I am using the search feature now.
I am just surprised there is not more narlow info on the web he worked on the case the longest right ?
I am really looking to find out who where his top suspects.

Somewhere I read or heard Narlow’s POI was a person who was in a Mental Hospital or something, in Napa County.

Sandy Betts says Ken Narlow’s favorite suspect was Rick Marshall: http://zodiackillersite.com/viewtopic.php?p=8894#p8894

Also, Mike Butterfield says:

Retired Zodiac investigator Ken Narlow said of the man often referred to as his “favorite” suspect, “Marshall makes good reading but not a very good suspect in my estimation.”

I haven’t yet found info on any other suspects specifically mentioned by Narlow.

Ken discussed Gareth Penn with me and how he threw him out of his office. I wish Ross Sullivan had come to light before Ken Passed, I would have loved to have asked Ken if he knew about Ross.

How about contacting Kens family and seeing if they have kept any note books of his.
