WORCESTER, Mass. (WWLP) – A detention hearing was held Thursday in Worcester for Jack Teixeira, the Massachusetts Air National Guardsman accused of leaking classified documents online.

A federal magistrate judge put off a decision Thursday on whether to detain 21-year-old Jack Teixeira until his trial begins. The prosecutors built up a solid case for detaining Teixeira, stating that he kept an arsenal of weapons and tactical gear at his North Dighton home, poses a flight risk and violent and racist comments online, including remarks about a mass shooting.

A former Massachusetts supreme court justice details what will unfold next in the case over the next few months.

John M. Greaney, senior counsel at Bulkley and Richardson, a former member of the Massachusetts supreme judge said, “They’ll add perhaps additional charges, they’ll decide where he’s going to be tried, most likely near Washington, probably in the eastern district of Virginia where the security agencies are located and eventually he’ll be brought to trial in front of a jury.”

Teixeira was charged under the espionage act with unauthorized retention and transmission of classified defense information. Teixeira entered his detention hearing Thursday in orange prison garb, smiling at his father in the front row.

Federal prosecutors will urge a judge to keep Jack Teixeira served with the 102nd Intelligence Wing at Otis Air National Guard Base on Cape Cod. Prosecutors say Teixeira, had detailed discussions about violence and murder on the same platform on which he shared the documents.

While Teixeira, who is from the southeastern Massachusetts town of Dighton, was arraigned in federal court in Boston, Thursday’s hearing was held at U.S. District Court in Worcester. The detention hearing was originally scheduled last week in Boston but had been delayed.
