In part one of the series, "Walk in My Shoes," Holmes talked to one of the teens who participated in the brawl that left a 16-year-old boy dead.
Part two examines “Why do teens fight?” Holmes talked with a group of teens who say acts of violence help to protect their reputations.
In part three Holmes traveled with two students in Chicago and witnessed some of the threats these teens face going to and from school.
In the last installment of this series, Holmes talked to specialists about the teenage brain. Teen’s brains are still developing, so if put in a volatile situation, their processing of that situation results many times in overreaction or misinterpretation of the situation.
