BOSTON MARATHON-MEDAL

BOSTON (AP) — The winner of this year’s Boston Marathon has returned his medal to Mayor Thomas Menino. Lelisa Desisa of Ethiopia did so to honor the city and those killed and injured in the bombings near the finish line two months ago.

More than 6,400 athletes gathered on Boston Common for the 10K organized by the Boston Athletic Association.

A moment of silence paid tribute to the three victims killed in the April 15 bombings and to Sean Collier, the MIT police officer who was shot and killed three days later during a search for the suspects.
