Both Hamzat Umarov and his wife Raisa Umarova insisted in separate interviews that Heda stayed in Chechnya to get married. Raisa Umarova said that the future groom is "lovely" and that Heda met him during Ramadan services during the family trip.
The family, however, would not provide details on the wedding and declined to identify the groom to ABC News. Sources said law enforcement officials were similarly stonewalled.
Tsarnaev has been held in a Massachusetts federal prison at Fort Devens since his arrest and the Department of Justice has announced prosecutors will seek the death penalty. Tsarnaev is also charged with the assassination of MIT Police Officer Sean Collier, who prosecutors said was gunned down by Tamerlan and Dzhokhar Tsarnaev on April 18.
U.S. District Court Judge George A. O'Toole ruled last month that the trial is slated to begin in November and allowed the defense team to add another death penalty attorney to work on the case. Last week defense attorneys complained in a court filing that the FBI is monitoring every file that they review with Tsarnaev, endangering his right to a fair trial. Much of the court filings on the case are under seal.
