The FBI said it has received a “tremendous” amount of video from the public taken near the Marathon’s finish line where bombings killed three people and stunned the nation Monday.
Crucial evidence could turn up in video shot on smartphones and other recorders. The challenge: How to sort through all those images quickly and effectively.
Experts say analyzing so much content is a mountainous task and believe it will take months to process the digital evidence from what Boston police commissioner Edward F. Davis called the most photographed event in the country that day.
“It’s a very tedious process,” said Andrew Obuchowski Jr., an associate director at Navigant Consulting Inc. in New York and a former law enforcement forensic video analyst. “Trying to be able to get through it quickly is a challenge.”
The process is cumbersome due to the limits of software that automatically processes such content. Investigators still must watch most of it and then enter information into a database by hand.
