A Massachusetts man crossed the finish line of the Boston Marathon in memory of his three children, who were killed last year. Patrick Clancy ran the 26.2 mile race Monday while wearing the names of his children -- Cora, Dawson, and Callan -- on his bib, and wearing an item that belonged to each child: A hair bow of 5-year-old Cora's, a wristband of 3-year-old Dawson's and a bracelet of 7-month-old Callan's, he told WCVB-TV, the ABC station in Boston. "They were my motivation," Clancy said of his kids in an interview with WCVB-TV after the race.
