Chechen brothers in Boston manhunt led ordinary lives
Neighbours, classmates, coaches shocked by pair's link to blasts; they were set up, dad says

Tamerlan Tsarnaev practiced martial arts and boxing, even aspiring to fight on the US Olympic team.
Dzhokhar Tsarnaev had been on the wrestling team at a prestigious school and won a scholarship from his city to pursue higher education.
Neighbours recalled the ethnic Chechen brothers, living on a quiet street in Cambridge, Massachusetts, riding bikes and skateboards.
Yesterday, after hours of only grainy images of two men in baseball caps to go on, a portrait quickly emerged of the men, one now dead, suspected of carrying out Monday's deadly Boston Marathon bombing.
The brothers, who came from a violence-wracked Russian region, lived together and had been in the country for about a decade, according to an uncle, Ruslan Tsarni, who lives in the US state of Maryland. He said the brothers "grew up in Kyrgyzstan" - a Central Asian republic.
