One year ago Tuesday, two  bombs went off near the finish line of the 117th Boston Marathon, killing three people and injuring more than 260. A week of ceremonies is planned to honor the victims, first responders, medical personnel and others ahead of this year's marathon, which will be run April 21.

Monday and Tuesday, I'll be blogging about those tributes and some of the people affected by last year's terrorist attacks.

Here are some stories I've written about the victims over the past year:

Doctors work to save victims' legs.

Injured survivors begin next phase of recovery.

Amputees worry charity money won't be enough.
