October 2, 2002. A bullet pierced the window of a crafts store in Maryland, just missing the cashier. But other bullets hit their targets. In Pursuit follows the hunt for the Beltway snipers during the twenty-three-day shooting spree that terrorized Maryland, Virginia, and the District of Columbia. David Reichenbaugh, the criminal intelligence operations commander for the Maryland State Police, and commanding officer at the scene during the snipers' capture in Myersville, Maryland, played a major role in the investigation from the first day of the killing spree through its final act, as the snipers were cornered in a rest area in western Maryland. He is one of a very few who know the complete details of the investigation and capture of the snipers. Working against the clock with few clues and little evidence, hundreds of investigators from federal, state, county, and city law enforcement agencies struggled to find answers to the questions: Who were the killers? Was their choice of victims random? And most of all, Why did they kill? When the killers began leaving notes to taunt the police, investigators were finally able to begin assembling a picture, piercing the fog of uncertainty and terror that filled the region. In Pursuit is a step-by-step procedural that offers an inside look at how investigators made sense of the dizzying array of facts, conjectures, motives, and opportunities and brought to heel two of the most diabolical killers in the nation's history.
