CANADA Canada - Mary Ann Plett, 29, Edmonton AB, Sept 15 1971

So, from 1973 - 1981 we have the TransCanada Highway Murders of which a few were either contemplated or put on the HOT list.

Probing the mystery of Edmonton’s killing fields
Aug 5, 2017
"Homicide count for females in Edmonton
We identified 49 such cases since 1986. Our collection is in no way representative of the larger number of female homicides in Edmonton during the same period, and we may have overlooked relevant cases. Nonetheless, these 49 cases shared striking characteristics."

And Edmonton is the direct route to Prince George and the Highway of Tears. Highway 16 seems to have kicked off in around 1989 and about the same time that the Killing Fields of Edmonton kicked off. It would seem as if these three areas are directly connected and if that is so then we know that he is at least in his late 60's and would have been in his early 20's at the time of Mary Ann's abduction and death. There are too many connections and too many similarities to not believe that this is the same man. Most likely he was born and raised in Edmonton and sometime between 1971 - 1973 he moved which accommodated the travel between BC and Alberta along the southern route and then between 1981 and 1986 he moved back to the Edmonton area where he's been ever since.
Makes sense.
A thought- perp attended a university or other training school in BC after graduation, then returned to Edmonton? Confidant on the phone ... actor, salesperson?speculation.
 
Mary Anne Plett - look at

Edna Macdonald of Barrington Rhode Island 1971...April...

Look at Iowa Cold Case Dorothy Miller - look who got sketched. ..1969...

1982 Jean McPhaul Louisiana....

Also someone here correctly connected the baby sitter Kelly Cook. That’s him too. .

I'm thinking that he lived in B.C. over this period of time and was driving back and forth for business. A con man who most likely was attempting to run his own business and we all know how that would go with his mind on hunting women. Probably not overly successful and full of sh!!... MOO

I'm running with Alberta, B.C. and less travelled Saskatchewan. That seems like enough territory to cover with numerous connections and Kelly Cook is on the TransCanada Highway murders list in which a few of those names have been connected to the Highway of Tears list. So, back we go to the comfort zone and that comfort zone would seem to be Edmonton for all intense purposes, a place where he can hide and a place where hiding isn't really that difficult. Now, keeping this in mind we need to ask ourselves one question and that is, did we hear his voice on the Amber Tuccaro cell phone recording? Because that voice is the voice of a well seasoned con man with more than a few years of conning women out of there lives and IMO all of those years of sliding down the highway has turned him into a fat slob. It's the dynamics of sitting on your *advertiser censored** all your life behind the wheel and living a slovenly lifestyle that goes with slovenly behavior. And this brings us to a distinct possibility that we are looking for an older fat slob who resides in Edmonton.
 
To be very clear, Mary Ann Plett picked up a client at a mall in Edmonton with the intention of showing him a property in Looma, southeast of Edmonton. The property in Looma was searched thoroughly, including draining a large body of water.

However, her remains were found by chance months later, far from where she was headed on her final day, northwest of Edmonton, near Fort Assiniboine.

Her killer was reported to have made multiple phone calls to her, requesting viewings of rural properties. Another female realtor was later revealed to have received phone calls from a man who used a similar pseudonym, requesting viewings. She declined.

This seems to indicate persistent stalking-type behavior. I can think of another murder preceded by multiple phone calls to two females, in southern Alberta. In that case, one lived by turning down the man's request, and one did not.

A man with the initials J.C. called Mary Ann Plett. A large body of water was searched for Mary Ann Plett, but she was not found there. Mary Ann Plett's last client claimed to work for a pumping company.

A man with the initials J.C. called Kelly Cook. Kelly Cook was found in a large body of water. Kelly Cook's killer had some kind of logo on his jacket. Strathmore, near Kelly's home town of Standard, has offices for the Western Irrigation District. Irrigation canals run through this area.

"James Cooper" called Mary Ann Plett. Soon after she disappeared, "Dave Cooper" called another female realtor in Edmonton for a viewing of a rural property near Edmonton.

A decade later, A girl in Standard, Alberta and Kelly Cook got a call from a "Bill Christensen".

These were three very common given names for men at the time. The three surnames begin with "C".

The search for Mary Ann took investigators to water. Kelly Cook was found in an irrigation reservoir.

Another thought about Mary Ann's killer being from Edmonton & area. He picked a real estate agency on Whyte Avenue. Mary Ann picked him up at the Bonnie Doon Shopping Centre on Whyte Avenue. Her car was found at a Don Wheaton Chev dealership on Whyte Avenue, across the street from the former Inn on Whyte hotel, which had a busy bar with live music in those days. This area has and had a lot of low-rise walk-up apartments. Just down the street and around the corner on 104 St. was a Greyhound Bus pickup and drop-off location. Whyte Avenue has a direct city bus route to Bonnie Doon mall, a short bus ride away. Mary Ann's killer could have plotted this whole thing from across the street. I assume the guest registry at the hotel was checked, and questions were asked at the bar.
 
Mary Ann's married name, Plett, is a Mennonite name. Tofield and Lindstone were settled by Russian Mennonite immigrants in the early 20th century. Was the property for sale in Looma owned by members of that faith community? Did Mary Ann feel comfortable picking up a male client to tour a rural property because it was owned by people of faith and felt safe, or were those just vastly different, trusting times? Mary Ann was described as "deeply religious", although I don't know her religion.

Was anything ever disclosed about the property owners?

FYI, there is a Mennonite Heritage Farm about 10 minutes away from Looma.
