The death of a family member is one of the most traumatic things a person can experience. For Steve Johnson, his brother Scott's death almost 30 years ago is still a source of pain.

Scott Johnson was outwardly happy, about to finish a PhD and he was in a long term relationship. Police said his death was suicide.

But now, thanks to Steve, doubt has been cast on not only what the police said but what they did in response to Scott's death, and many others.
