"I'm surprised that (the court) fully granted the prosecutor's request, kept in place the arrest (as the measure of restraint) and set a two-month term," Sonata Zukauskiene told reporters.
The lawyer said her client would appeal the court's decision.
Venckiene is suspected of refusing to obey a court order, resisting a police officer, hindering a bailiff, and hitting Laimute Stankunaite, the mother of her niece, in the face. She is asking for a milder measure of restraint.
She fled Lithuania in 2013 and was arrested in Chicago in February 2018.
