Formerly a computer programmer, Browne strongly believes in newsroom innovation and in the capacity of technology to strengthen journalism. Browne is from Broadford, County Limerick, and lives in Dublin. He tweets @malachybrowne3. One of the iconic videos of the tragic 20134 Boston bombings was filmed by an athlete running her final mile of the marathon. As she approached the finish line on Boylston Street, the second bomb detonated meters ahead. It was a compelling video, but we needed to verify it. One photo showing the moment of the blast was posted by Boston journalist Dan Lampariello (below), a member of one of our pre-curated Twitter lists, and someone familiar to Storyful. Lampariello’s tweet was geolocated to Boylston Street; this information, which came from a reliable source, helped to confirm the location of the explosion. It also gave us a reference point to use with what was shown in the runner’s video. 54
