According to the U.S. Department of Justice, homicides committed by young people, ages 12 through 17, peaked nationwide in the 1990s. In Indiana, over 300 teenagers committed murder in that decade, and three quarters of them used a gun. In the last decade, only about 130 Indiana murders were committed by teens, but 79 percent of those involved a firearm. Homicide is only a small part of the story, as Y-Press journalists learned when they set out to report on teens and illegal gun use in Indianapolis. Peter Shirley, age 18, has this report written by Carmela Verderame.
