police investigators have been working to establish a 40-year timeline of Fowler's movements, but are seeking more information about his time in B.C. from the public.
"Our challenge has been determining with certainty Fowler’s history here in British Columbia," Shinkaruk said.
"We believe there are people out there who employed Fowler, worked with him, socialized with him or even waited on him while he was in British Columbia. We are asking you to think back to the 70s, 80s and 90s and your own memories of that that time period, then have a look at his photos, and please call us with any information you may have about him."
Police say Fowler worked for Happy's Roofing, a Prince George roofing company that is now out of business, in 1974.
They describe Fowler as an itinerant traveller, sometimes charming and often violent, who took odd jobs, lived in hotels, drove cheap cars, picked up hitchhikers and hung out in small-town bars.
"He believed that the vast majority of women that he met in those places not only desired to be sexually assaulted, but desired to be violently sexually assaulted," Shinkaruk said.
