Colorado man who says he was ‘almost a school shooter’ talks to WGN

Since the shooting that killed 17 people at Marjory Stoneman Douglas High School, much has been discussed about gun control, mental health and what drives someone to commit such a horrible crime.

Shortly after that shooting, a man from Colorado wrote a letter to a TV station in Denver -- saying "I was almost a school shooter."

In the letter, Aaron Stark said, "I didn't carry out anything, I didn't hurt anyone. But in 1996, I almost did the worst possible thing."

The letter has gotten a lot of attention in recent weeks.

Stark joined WGN Morning News Monday to talk about his letter, and what led him to "almost" become a school shooter.
