BOSTON — Massachusetts is planning to honor those who lost their lives in the Sept. 11 attacks 15 years ago.

There will be a wreath-laying ceremony at 7:30 a.m. Sunday at the permanent memorial located in the Boston Public Garden.

The annual name-reading ceremony of the more than 200 people with Massachusetts connections who died in the attacks will be moved indoors to the House Chamber due to forecasts of rainy weather. The ceremony typically takes place on the Statehouse lawn.

There will also be the awarding of the Madeline Amy Sweeney Award for Civilian Bravery.

Sweeney, an Acton resident, was a flight attendant on American Airlines Flight 11, the first of two planes hijacked from Boston. She is credited with discreetly contacting authorities and providing key information about the hijackers.
