CHICAGO – There are likely many factors that led Tamerlan Tsarnaev to allegedly mastermind the recent Boston bombings.
Some experts who track immigrant youth say feeling ostracized might have been one of them — and that he may have been more detached from American life than his younger brother, Dzhokhar Tsarnaev.
The younger Tsarnaev, seemingly the follower of the two, came to this country around age 9. That makes him a member of "Generation 1.5" — young people who were born in other countries but who came to the United States between the ages of 5 and 12. Experts say that age group often adapts better than their older siblings.
The ongoing investigation may shed light on how the younger brother allegedly went so wrong anyway.
