MOSCOW, April 18 (RAPSI) - One of the suspected Boston Marathon bombers that remains at large may have been a Kyrgyz national from a family of refugees, a Makhachkala school formerly attended by the suspect told RIA Novosti.

The suspect was identified as 19-year-old Dzhokhar A. Tsarnaev, of Cambridge, Mass.

The AP quoting its own undisclosed sources reported earlier that bombers come from a Russian southern region boarding Chechnya. According to mass media reports 19-year-old Tsarnaev managed to escape while his brother Tamerlan was killed in a confrontation with police.

Two blasts occurred at the finish line of the Boston Marathon, America’s most prestigious 26.2 mile race which boasts such stringent entry requirements that only the best of the best are entitled to compete. Three people have been confirmed dead, including an eight-year-old boy present to cheer on his father. The Boston Police Department tweeted in its latest casualty update Tuesday that 176 injured have gone to local hospitals. A large-scale, multi-agency investigation is presently underway.
