Drones as Detectives: Surveying Crime Scenes for Evidence

When detectives and other forensics specialists arrive at a crime scene, there is a pressing need to survey the area quickly. Environmental disturbances such as wind or an incoming tide could ruin valuable evidence, and even the investigators themselves are at risk of contaminating the crime scene.

Pompílio Araújo, a criminal expert for the Federal Police of Brazil, is responsible for recording crime scenes exactly as found. In his other role as a researcher at the Intelligent Vision Research Lab at Federal University of Bahia, he is trying to make his first job easier by developing drones that can—very quickly—home in on a piece of evidence and record it from multiple angles.
