Authorities said they know of no link between the Times Square bomber and the two accused Marathon bombers, other than the coincidental connections to Watertown.
Now, just more than a month after the bombings, windows in the Watertown area where hundreds of bullets were fired and four bombs were lobbed at police remain webbed with bullet holes and marked with FBI tape.
An ATF evidence cone marked "58" rests in a tulip bed. The vinyl siding of several homes is ripped with ricochet rounds.
The street is stained black from a pressure-cooker bomb.
