Rideau Hall on July 2, Corey Hurren tried to explain himself in a two-page letter now in the hands of investigators.“I hope this hasn’t been all for nothing,” the 46-year-old Manitoba military reservist allegedly wrote. “I hope that I will be forgiven and it is understood why I did this, especially by my children.”But the letter, whose contents were shared with Global News by a source, is not so much an explanation as a list of everything that seemed to be was going wrong in his life and how he framed it.It mentions his struggling business, the impending repossession of his truck, how he was not looking forward to more COVID-19 isolation, and his late father and brother.
