The military veteran who died by suicide on the steps of the Alberta legislature on Monday was a quiet man who would help anybody in need, his family says.

Ken Chan was not the type of person to try to draw attention to himself, said Harald Linder, who thinks Chan, his stepfather, suffered from depression and possibly post-traumatic stress disorder.

"He probably had a lot of pain that he just kept inside, depression being one of them," Linder said on Tuesday.

Chan was a retired army veteran who served his country for 25 years.

Not long before he died, Chan sent two emails. One was directed to his boss and co-workers at the trucking company where he worked, complaining about a lack of respect but expressing love for his fellow employees.

The other one was directed to the federal and provincial health ministers regarding medical assistance in dying, advocating for greater access. Chan wanted to bring attention to MAID, though Linder isn't sure why he focused on the issue.

Both emails were sent simultaneously about 25 minutes before Chan's death.

Linder said he's sad that his stepfather felt he had to take his own life.

"I can't change the past, but it's too bad a really good man had to do that."

He said he hopes that by discussing the death he may be able to help someone else in crisis.

"Try and love yourself and try and love the ones around you."

A funeral for Chan is scheduled for Saturday.
