One of the brothers suspected of carrying out the terrorist attack on the Boston Marathon faced deportation in 2009 after being convicted of a domestic violence charge but was allowed to stay, according to a government watchdog.

“Tamerlan Tsarnaev, the 26-year-old killed in a wild shootout with police, was a legal U.S. resident who never the less could have been removed from the country after a 2009 domestic violence conviction,” Judicial Watch reports based on an unnamed source.

Judicial Watch pointed out another coincidence: the other suspect in the bombing, Dzhokhar Tsarnaev, received U.S. citizenship on September 11, 2012, the 11th anniversary of the 9/11 attacks and the same day that terrorists attacked the U.S. mission in Benghazi, Libya.

CNN’s Wolf Blitzer mentioned that Dzhokhar Tsarnaev received citizenship in September, but he didn’t mention the exact date.
