The sister of accused Boston Marathon bombing suspect Dzhokhar Tsarnaev turned herself into authorities today to clear up a nearly three-year-old default warrant for her arrest and was released without bail by a South Boston District Court judge.

Ailina Tsarnaeva, 22, of Fairview, N.J., tried to hide her face as her attorney George Gormley rushed her into the back seat of an idling SUV. Both refused comment.

Gormley told Judge Michael C. Bolden Ailina Tsarnaeva, formerly of Cambridge, has another child at home.

Judge Michael C. Bolden waived Ailina Tsarnaeva’s next scheduled court appearance — Dec. 4 for a pretrial conference — on the condition she call into Massachusetts probation officials once a week while her case is pending.

Assistant Suffolk District Attorney William Champlin IV sought to have Ailina Tsarnaeva, formerly of Cambridge, held on $1,500 cash bail, noting she vanished after skipping out on a Feb. 24, 2011, court hearing on a case related to the passing of counterfeit money at Applebee’s Restaurant at South Bay Mall in Dorchester, and now lives out of state.

But Gormley argued, “This is a voluntary surrender appearance to get back in good standing with the court with a view toward defending this case. My client is practically indigent. She has no money, The bail of $1,500 might as well be $15,000. She’s unlikely to flee. She has a young child. She’s pregnant now.”

Gormley did not explain how it was Ailina Tsarnaeva could afford her own defense team.

Ailina Tsarnaeva pleaded not guilty Jan. 13, 2011, to what Champlin said was “misleading and impeding an investigation” into the counterfeit money case. She was released on personal recognizance. Prior to being charged she told police “she did not want to be a snitch.”

According to police records released yesterday, on April 16, 2010, while Ailina Tsarnaeva was still living with her family on Norfolk Street in Cambridge, counterfeit money was used to pay a tab at the restaurant and her car was used by the diners police were seeking for questioning.

“She did agree that her car was used and she was there,” Champlin said today, “but then was uncooperative as to who the other parties were.”

Ailina Tsarnaeva told police she was out with friends, but didn’t know their names, and later dropped them off at South Station.

In an official investigation report, Boston Police Detective Robert J. Kenney wrote, “I pointed out how unbelievable the story was.”

The young woman’s mother, Zubeidat Tsarnaeva, told Kenney her daughter had moved to a shelter because she felt her mother was “too strict,” a police report states.

Within the next two weeks, federal authorities in Boston will submit their recommendation to U.S. Attorney General Eric Holder as to whether they want her brother Dzhokhar Tsarnaev, 20, put to death if convicted of what federal prosecutors said in court papers filed last night was “the most serious terrorist attacks against civilians on American soil since Sept, 11, 2001. He is charged with brutally murdering two women and a small child; maiming, blinding and deafening scores of others; carjacking a victim and then robbing him; executing a police officer; and then attempting to murder other police officers with bombs and gunfire.”
