PHOTOS: March for Justice for Trayvon Martin

BOSTON/Roxbury - Close to 300 people - led by African-American students in the new Boston4Justice network - marched from the Ruggles MBTA Station to Dudley Square on Saturday to demand that George Zimmerman, the confessed killer of Sanford, FL teen Trayvon Martin, be put on trial for murder. The event was peaceful. There was a moderate police presence, no incidents and no arrests.
