His video-sharing account features a playlist entitled "terrorism," even as two videos under the list was deleted by the author at some point in time, before the bomb blasts at the Boston Marathon, which killed three and injured over 180. The account contained links to a number of videos about Islam, as well as videos of a Chechen singer Timur Mutsuraev.

Federal agents on Sunday made three visits to the her parents' Rhode Island home, according to the New York Daily News.
Her lawyer Amato Deluca later said, "I spoke to [officials], and that's all I can say right now. We're deciding what we want to do and how we want to approach this."
DeLuca did not offer new details of where Tamerlan Tsarnaev was in the days after the bombing last week, adding that the last day he was alive that "he was home" when his wife left for work. He wa killed in a shootout with police.
DeLuca said she learned about her husband being a suspect from seeing it on TV. His wife reportedly had been working 70 to 80 hours weekly as a home health care aid, while he took care of their 3-year-old daughter, news reports said.
Katheine Russell had been raised Christian but converted to Islam during her courtship and marriage to Tsarnaev.
