The Wall Street Journal has produced an insta-profile of the suspected Boston Marathon bombers, Dzhokhar Tsarnaev, 19, and Tamerlan Tsarnaev, 26. Tamerlan died last night following a clash with authorities.

According to the piece:

The family, which included two boys and two girls, had come to America to seek refuge from the war in Chechnya, where an Islamist rebellion had been crushed by the Kremlin under President Vladimir Putin. But soon after arriving their efforts to adapt quickly ran into headwinds.

Anzor Tsarnaev, the father, is described as a “talented car mechanic” with ambitions of opening his own garage, but never did.

The noteworthy graph in the piece is this one:

Both boys were good students, and the elder, Tamerlan, aspired to be a professional boxer, the family friend said. But he dropped out of community college and was soon drawn into religious matters, he said. Dzhokhar “had a gentler demeanor,” the family friend said, but had also apparently taken a deeper interest in religious affairs.

Just what sort of religious affairs did these brothers sink themselves into? The Wall Street Journal doesn’t go there, a decision that reflects a wider reluctance within the media to get too particular about these brothers’ background, possible motivations and allegiances. It is, after all, just 18 hours since authorities released photos of the two.

“What we’re dealing with most is what we don’t know,” said Chris Cuomo moments ago on CNN. “We don’t know their motivations…”
