There are a number of references to dating sites for MR.
In one he refers to being 25 and having moved from Toronto to Guelph, two years ago. Looking for "mrs wonderful" for "foreverness". He lists his education as BA/BS 4 yr . He also appears on a Christian dating site at this time looking for a "single Christian girl to hopefully some day marry". At that time he was "working in construction" and "working on becoming a paramedic".
Two- three years later he is found on another dating site still seeking a long term relationship but listing himself as being a professional dance instructor and running a contracting business. Location Woodstock Lists his smarts as having a graduate degree.

I also came across another originating when he was 25 ( he includes a photo of himself) searching for "mrs right" He says he was originally from Toronto and having lived in Guelph for 3 years at point and working in construction. It is a Guelph dating site offering live chat.
It would appear that this young man has been searching for the right woman to form a committed relationship for at least 3 years. Moving around while doing so. Toronto, to Guelph, to Woodstock. It can become difficult to meet people and it is becoming more and more popular to connect with others through a dating site. Thanks to the internet it is easier to meet others with the same interests or goals. Unfortunately it can also lead to meeting those who have ulterior motives.
There is no way to actually enter or understand the mind of an individual who finds themselves charged with such a hideous crime. These online footprints to me only suggest a lonely individual, seeking a relationship with a member of the opposite sex. By information he provided on these sites he was tired of "games" and was looking for "the one".
Proclaiming to be religious or to not be religious, and willing to change some things about himself for the "one" relationship.
