Ten years later, my wife and I have no idea why Brett committed suicide.

Most people feel that individuals who commit suicide are the downtrodden. Most are very, very bright overachieving individuals.

She had a lot of depression in her life, but she didn't want to share it with anyone.

He became more quiet and more into himself a few months before he took his life. I didn't pursue it.

It was 10 years ago that Brett took his life.

There had been some altercation between them. It looks like a probable suicide (on his part).
