A mix of old-fashioned legwork and high-tech razzle-dazzle, scouring hundreds of hours of surveillance videos, helped police home in on suspects in a Hamas man's slaying, blamed on Israel's Mossad.
"Using facial recognition software, a source familiar with the investigation said, a team of 20 investigators pored over hours of security camera videos to sketch out a picture of the suspects' movements and accomplices, a group that has grown to at least 27 people.
They tracked down taxi drivers and grilled them about the suspects. They even traced the trip of a female suspect to a shopping center and discovered what she bought."
