A federal grand jury in New York has indicted a 20-year-old Augusta-area woman, accusing her of providing material support to the Islamic State.

Kim Anh Vo pleaded not guilty to the indictment last week. If convicted, she could face up to 20 years in prison. Her court-appointed attorney, Sabrina Shroff, declined to comment about the case Tuesday.

Authorities arrested Vo last month in Hephzibah, Ga., for allegedly participating in and recruiting others to join an online hacking group that has pledged allegiance to the Islamic State, or ISIS. The group, United Cyber Caliphate, disseminated ISIS propaganda online, stole information from private and government computer systems and published videos online that call for Islamic State supporters to murder thousands of Americans, the Federal Bureau of Investigation says in a March 8 request for a warrant for Vo’s arrest.

Unnamed co-conspirators in the Netherlands, Norway and Iraq are mentioned in the court records. One is accused of posting a link to an online video threatening a nonprofit organization in New York. Another is accused of posting, on behalf of ISIS, a video publicizing the upcoming release of a “kill list” of more than 8,000 people, including some in New York.
