( CNN ) Silent , almost shy as she headed into Manhattan Criminal Court , Ailina Tsarnaeva was anything but timid when it came to a perceived rival , prosecutors say . According to a criminal complaint , Tsarnaeva threatened a woman in a phone call this summer , saying `` Leave my man alone . '' `` Stop looking for him . ... I know people that can put a bomb where you live , '' she said , according to the complaint . Considering who was making the threats , prosecutors did n't consider it a joke and charged Tsarnaeva with aggravated harassment , which she denies . Leaving court last December , she and her lawyer refused to discuss the case . Tsarnaeva is the sister of Dzhokhar and Tamerlan Tsarnaev . Authorities allege the brothers are responsible for the 2013 Boston marathon bombing , which left three people dead and more than 260 others injured . Police shot and killed Tamerlan Tsarnaev , 26 , during the manhunt and later captured Dzhokhar , who is now on trial . Tsarnaev 's lawyers do n't dispute that he did it . The defense argues that he was influenced and enlisted by his older , self-radicalized brother to commit acts of terror . Defense rests in Boston Marathon bombing trial . The Tsarnaev family first immigrated to the Boston area back in 2002 . The parents , fleeing a troubled region of Russia , were treated as legal residents and granted asylum -- a status that opened the door for taxpayer-funded welfare . The state of Massachusetts has confirmed the Tsarnaevs received food stamps , public housing and other aid , on and off , between 2002 and 2012 . During this time , Tamerlan Tsarnaev began his conversion to radical Islam . Then , according to investigators , he began filling his younger brother 's head with a hatred toward the West . Not much is known about the two Tsarnaeva daughters , Ailina , 24 , and Bella , 26 , though their last known address was in North Bergen , New Jersey . Along with charges of making bomb threats , Ailina Tsarnaeva has a past record that includes misleading police in a counterfeiting case . She pleaded guilty but got no jail time . She was also charged with leaving the scene of an accident , but that charge was dismissed . Her older sister , Bella , was charged with marijuana possession and intent to distribute after a 2012 arrest , and she entered a pretrial intervention program . Even their mother , Zubeidat Tsarnaeva , has had issues with the law . She fled back to Russia in 2012 , where she remains a fugitive . Records show that she was arrested in June 2012 for allegedly shoplifting $ 1,600 worth of women 's clothing from a Boston-area Lord & Taylor department store . She is wanted on felony charges of shoplifting and destruction of property . Russia raised concerns to U.S. authorities about her in 2011 at the same time they asked the United States about her son Tamerlan , several sources told CNN shortly after the 2013 attack . U.S. authorities added the mother and son to the Terrorist Identities Datamart Environment , or TIDE , database -- a collection of more than a half-million names maintained by the National Counterterrorism Center , an intelligence official said . FBI agents interviewed Zubeidat Tsarnaev as part of the investigation into her son , whose case was closed after several months . The radicalization of Tsarnaev . In Russia , she has maintained her innocence in the shoplifting case while also calling the charges against her sons `` made up . '' Though not elaborating on her beliefs , Ailina Tsarnaeva has said she believes , as her mother does , that her surviving brother Dzhokhar and her dead brother Tamerlan are innocent . Dzhokhar Tsarnaev , now 21 , faces 30 criminal counts , including using a weapon of mass destruction causing death . On Tuesday , one day after federal prosecutors rested after calling more than 90 witnesses , defense lawyers rested their case without calling Tsarnaev to the stand . Closing arguments are expected Monday . Tsarnaev attorney : 'It was him ' Watch Erin Burnett weekdays 7pm ET . For the latest from Erin Burnett click here .
