After being sentenced to 15 years in prison on federal charges for her role in a child pornography ring, a woman who used to live in Suffolk now faces state charges as well.

Sierra Danyelle Halsey, 24, was indicted by the grand jury on March 5 on 22 charges, including sodomy, aggravated sexual battery, indecent liberties and cruelty to children.

According to city spokeswoman Diana Klink, Halsey was the girlfriend of Robert H. Scott, also known as “Mike Pyro.” From November 2012 to April 2013, he extorted money from women who hosted sex parties at area hotels, and he solicited child pornography from at least five women via email and text message.

Halsey made pornography videos with at least two male victims, ages 1 and 5 years old, at her former residence in the 5000 block of Townpoint Road in Suffolk in April 2013.

Scott promised to pay Halsey $150,000 for the child pornography but never paid her, according to Klink.

Halsey confessed to her involvement after being arrested in April 2014 by Department of Homeland Security agents while she visited Scott at the Western Tidewater Regional Jail. She pleaded guilty in U.S. District Court to production of child pornography and destruction of records.

After the completion of the federal investigation, a separate investigation was initiated by the Suffolk Police Department and Suffolk Commonwealth’s Attorney’s Office, resulting in the new charges.

Halsey is incarcerated at Western Tidewater Regional Jail as a federal inmate.
