The bombs that turned the finish line of the Boston Marathon into a war zone were made of 6-liter pressure cookers with shards of metals, nails and ball bearings.
Security incidents were reported at two known U.S. airports on Tuesday morning, one day after two bombs detonated during the marathon in downtown Boston on Monday. Sections of Laguardia Airport were evacuated on Tuesday morning following a report of a suspicious package.
Martin Richard, an 8-year-old boy was killed on Monday at the end of the Boston Marathon. The mother and sister were both critically injured in the blast. Martin's mother underwent brain surgery Monday night and his sister, 6, lost a leg in the blast. The status of his father, Williams, has not been released publicly.
Boston Police Commissioner Ed David said that there is not anyone in custody for the dual bombings at the Boston Marathon. Officials made a public plea to turn over any photographic or digital evidence they have from the scene.
