It's his second victory here. He also won the 2013 race just hours before a pair of bombs exploded at the finish line. Desisa returned after the attacks to donate his medal to the city in memory of the victims. Caroline Rotich (ROW-tish) won the women's race in an unofficial 2:24:55. It's the first Boston victory for the 30-year-old Kenyan. She finished fourth here in 2011. Two years after the bombs killed three and wounded 260 more, the world's most prestigious marathon took a tentative step back toward normal.
