(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 didn'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 don'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. 
Who is this mostly about? What is she accused of doing? How? When? What is her quote? Did she mention a specific weapon? Which one? Did the court consider it a joking matter? What did they charge specifically? Did she admit to it? Does she have any siblings? Who? What are they known for? When was that? Did anyone die from that? How many? How many hurt?
