On Thursday we didn't know who the Boston bombers were. All we had were pictures. By Friday morning, we had chilling details about who the terrorists really are.
The media has heard from dozens of people who knew the brothers. We continue to hear that they were normal.
Tamerlan Tsarnaev and his younger brother, Dzhozkar had family roots in Chechnya but came to the US from Russia as children. Their family moved to Massachusetts 11 years ago.
19-year-old, Dzhozkar came to the United States on a tourist visa in April 2002. He received permanent resident status in February 2007 and became a naturalized citizen on September 11, 2012.
26-year-old, Tamerlan was a golden gloves boxer. Someone who knew him called him religious.
Since Friday morning, three family members have talked to reporters. An uncle in Massachusetts called them, "losers", an aunt says she is suspicious of the FBI's story, and the boy's father says his sons were set up.
We also found out that the Tsarnaev's mother was arrested last year in Massachusetts for stealing women's clothing and damaging property.
