BOSTON (AP) — As bagpipes wailed, more than 4,000 mourners paid their respects Wednesday to an MIT police officer who authorities say was ambushed in his cruiser by the Boston Marathon bombers, while U.S. investigators trying to get to the bottom of the plot looked for answers from the Tsarnaev brothers' parents in Russia.
In a sign of how things were slowly and painfully getting back to normal in Boston, the area around the finish line on Boylston Street reopened nine days after the tragedy, freshly poured cement still drying on the repaired sidewalk.
On Capitol Hill, meanwhile, lawmakers are asking whether a failure to share intelligence may have contributed to the bombings April 15 that killed three people and wounded more than 260.
MIT students, faculty and staff, law enforcement officials from across the nation and Vice President Joe Biden gathered on the campus in Cambridge to remember Sean Collier, a MIT officer who authorities say was gunned down by Dzhokhar and Tamerlan Tsarnaev three days after the bombing.
The line of mourners stretched for a half-mile. They had to make their way through tight security, including metal detectors and bomb-sniffing dogs.
