Dzhokhar was widely considered by friends a reserved but nice guy. According to BuzzFeed, he attended Cambridge Rindge and Latin School and was commonly called "Jahar" -- because Dzhokhar was too difficult to pronounce. He was born in Kyrgyzstan, while his brother Tamerlan was born in Russia.

Friends said they were shocked to learn that he was involved with the Boston bombing.

Dzhokhar reportedly received a $2,500 scholarship to attend college and was listed as an all-star wrestler for the school in 2011.
