1. A high school classmate of Tsarnaev confirms to BuzzFeed that @J_tsar is his Twitter account:
“I would confirm this as to being his Twitter account. Those users went to my high school,” said Stefanie Gardner, of the Rindge class of 2011.
4. Brobible also writes they’ve reached out to friends of Dzhokhar, who confirm he went by the nickname “Johar”:
I DM’d with one Twitter user who is a student at the University of Massachusetts: Dartmouth (UMD) and who spoke a lot today, publicly on Twitter, about his relationship with him. He DM’d me back to say that he considers himself friends with the fellow UMD student. He confirmed that @j_tsar IS Tsarnaev’s Twitter account, but he asked that he not be brought into this. At least one point this year the person I DM’d with is RT’ed by @j_tsar, so I don’t think he’s lying about the relationship.
