Boston area honors slain MIT officer

BOSTON (AP) — As bagpipes wailed, more than 4,000 mourners paid their respects today 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 other developments:

— The bombs were detonated by remote control, according to U.S. officials close to the investigation who spoke on condition of anonymity because they were not authorized to discuss it publicly. It was not clear what the detonation device was, but the charges against surviving suspect Dzhokhar Tsarnaev say he was using a cellphone moments before the blasts.

— 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, lawmakers are asking whether a failure to share intelligence contributed to the bombings April 15 that killed three people and wounded more than 260.
