Some rumours in comments section of news links, suggest that she may be known to hang out regularly in coffee shops in the downtown area alone with her computer...IMHO there are a few cryptic things in the information available:
- looking at her linkedin profile page, she seems to have had no steady employment since graduating. The only thing confirmed is her education at York. She vaguely mentions briefly being a head of a 'mining company' that she doesn't name.
From the Star http://www.thestar.com/news/crime/2015/12/14/toronto-police-id-suspect-in-unprovoked-path-stabbing.html
-despite being unemployed, police describe her as regularly frequenting the financial district in Toronto. What does she do when she frequents the area?
-the police mention where she frequents, but not the area where she lives - what is her fixed address? Does she have one? Does she live with anyone? Why no appeals from family for her to turn herself in?
She's described as being very petite, and dressed in dark, common business attire. IMO it would be easy for her to go unnoticed. She was carrying a coat over her arm, what looks like a purse and another bag - all of which could have hidden her weapon and any possible blood.
My theory is that the Path, stores, and coffee shops might be her second home, possibly the place she spends most of her time. She is carefully made up to look as though she has business there, but does not. (Maybe pretending to go to work every day?) I think the police might find her eventually in a coffee shop acting as if nothing was amiss. Or, as we're close to Christmas, she'll show up at a relatives home.
It's easy to lose yourself in the underground paths. A few years ago a teen patient went missing from Sick Kids hospital and was seen heading into the Path. My nephew was at Sick Kids at the time, so a number of my family went to look for the teen. Dozens of police and volunteers went looking for him and I think it took about 10 hours to eventually find him, and only because he called a family member.
