Boston Marathon bomber Tamerlan Tsarnaev denied any links to terrorism only a few months before the April 2013 attack that killed three people and injured 260 others, according to federal documents obtained by The Boston Globe.

Tsarnaev, 26, who was killed in a manhunt after the attack, passed a U.S. citizenship test three months before he and his brother Dzhokhar set off the bombs, The Globe reported Sunday, citing redacted immigration records it received under the Freedom of Information Act.

Dzhokhar Tsarnaev was sentenced to death in May 2015 for his role in the attack.

U.S. Citizenship and Immigration Services, or USCIS, said in a statement Sunday that the cases of Tamerlan Tsarnaev and his friend Ibragim Todashev, who was killed in Florida by an FBI agent a month after the bombings, were handled correctly.

"While USCIS found no errors in the processing of Tamerlan Tsarnaev's or Ibragim Todashev's applications, we are always seeking to strengthen our very intensive screening processes," it said.
