Unsolved Shootings — Data, Code, and Methodologies

To gain a deeper understanding of America's unsolved-shootings crisis, The Trace and BuzzFeed News analyzed data from three historical FBI datasets, along with internal data obtained from 22 police departments. We also conducted a detailed analysis of Baltimore shooting victim and suspects. You can read about our main findings here:
