OTTAWA _ The mother of a Canadian soldier who killed himself in 2008 is expected to testify today at an inquiry into how the military handled his death.

Cpl. Stuart Langridge had been suffering from post-traumatic stress disorder after tours in Bosnia and Afghanistan when he died at a base in Edmonton.

The military had initiated several reviews into his death but his parents had raised concerns about those efforts.

Canada's military justice watchdog decided a public hearing was warranted and it began last month.

Langridge's mother Sheila Fynes has said that her son was never properly treated for PTSD and called decisions made by medical staff in the last weeks of his life were humiliating.

And after his death, military mistakes added to the family's suffering, including a mixup in the next of kin and a delay over 14 months to deliver his suicide note to the family.
