If you Google Highway of Tears you will see that it has not been ignored. It has been the subject of much inquiry but sadly most of the missing women cases have not been solved. The majority disappeared traveling (often hitchhiking) along the remote highway. Most were indigenous but some of the missing women were not.
The Royal Commission on Missing and Murdered Aboriginal Women addressed this also.
At least one serial killer, Cody Legebokoff, is implicated.
These issues do not lend themselves to easy solutions. You cannot just throw money at the problem. As a Canadian, I am very aware of our history. We are very open about our past and as I have stated, we are working at reconciliation. We are very far from perfect.
I say this as someone who went to high school in Kamloops, BC and lost two classmates who were brutally raped and murdered in 1973 (Gail Weys and Pamela Darlington). If they were indigenous I did not know. It was very scary to be a young woman attending college that Fall. It is generally believed they were both murdered by the same serial killer, but I am not up to date with the cases.
The Yellowhead Highway, called the highway of tears, starts at Kamloops and goes north through remote country. I think it is fair to say that young women hitchhiking along that highway was and is unwise regardless of ethnicity. At the same time, the distances and remoteness mean public transportation is not readily available.
There is much work to do.
