Greg Matters was a soldier for 15 years, his sister, Tracey, said on Thursday.
He left the Canadian Forces in 2009 and after he returned to his home town in northern British Columbia it became clear to those who loved him that Matters was suffering from PTSD, she said.
"There was a delay in him getting treatment," said his sister, who returned to Canada from Australia after learning her brother was dead.
"We actually, as a family, suspected he had post-traumatic stress disorder and we sought treatment independently."
About a year and half ago, he began treatment at the Operational Stress Injury clinic in Vancouver, one of nine across Canada funded by Veterans Affairs.
This is a different take on what I've heard. Fellow I work with has a brother who is (was) Greg's neighbor, he said the family had been trying to get help for Greg without results. He said Greg would dress up in camos and patrol the area. He was never armed, and was unarmed when they shot him. He was not getting treatment.
