While surveillance video provided key images of the men suspected of planting bombs at the Boston Marathon, police use of facial-recognition software proved unhelpful in revealing their identities.
Despite several images of Tamerlan and Dzhokhar Tsarnaev from the scene of the deadly bombings and the existence of images of the brothers in official government databases, facial-recognition software was unable to put names to their faces, Boston Police Commissioner Edward Davis told the Washington Post in an interview published Saturday. Dzhokhar Tsarnaev has a Massachusetts driver's license, while Tamerlan Tsarnaev, the elder brother who died Friday after a shootout with police, had been the subject of an FBI investigation, the Post noted.
After a dozen forensic experts spent days combing through hundreds of hours video and thousands of still images to construct a timeline of events, law enforcement use of facial-recognition software "came up empty," according to the Post. Conducted in a sprawling warehouse in Boston's Seaport district, the work was "painstaking and mind-numbing," according to the Post, with one agent reviewing the same segment of video 400 times.
