The Fulton County Sheriff’s Office mentioned Thursday that it was investigating on-line threats towards the grand jurors who voted this week to indict former President Donald J. Trump and 18 others, accusing them of conspiring to overturn Georgia’s 2020 election outcomes.

The jurors’ names are listed early in the sprawling 98-page indictment, as required in Georgia, making the state an outlier amongst federal and state court docket programs.

Now a few of these jurors have had their faces, social media profiles and potential addresses and cellphone numbers shared on web websites, in some instances with the suggestion that they need to be harassed — although it was unclear on Thursday if anybody had adopted up on these ideas.

The county sheriff’s workplace mentioned in a press release that it was conscious of on-line threats towards grand jurors and was working with different companies to trace down their origin. It didn’t reply inquiries about whether or not any jurors had reported harassment.

Other prosecutions of Mr. Trump have additionally resulted in threats. A Texas girl was charged this month with threatening to kill Tanya S. Chutkan, the decide in Washington who’s overseeing the federal election interference case towards the previous president.

The jurors within the Georgia case have been drawn from throughout Fulton County, the place the district legal professional, Fani T. Willis, spent two and a half years investigating actions by Mr. Trump and his allies within the aftermath of the 2020 election and introduced proof to the jury on Monday. Twelve of the 23 jurors have been required to approve an indictment.

Soon after the indictment was launched late Monday, some on social media started scrutinizing the jurors’ identities and revealing their private particulars.

“I thought it only fair to share a few names from that grand jury,” one person wrote on Facebook on Wednesday, together with potential addresses and cellphone numbers for a number of jurors. “I will continue to post the other jurors as I find them.” (The put up was later eliminated by website directors, a spokesman for Meta, Facebook’s father or mother firm, mentioned in an e mail.)

On Truth Social, the social media platform based by Mr. Trump — who has himself lashed out at prosecutors, judges and personal residents who’ve sued him — many customers reposted the names. In one response to an inventory of a number of jurors, a person urged others to make them “infamous” and to “make sure they can’t walk down the street.”

Media Matters, a liberal nonprofit that screens conservative media organizations, collected different messages posted on one on-line board that included threats of violence towards the jurors and known as the listing of their names and addresses a “hit list.”

The New York Times seen writings on practically a dozen channels of the messaging app Telegram, the place the jurors’ info was being shared. In a lot of these channels, claims have been made concerning the race or spiritual background of the jurors primarily based on their names or their politics. Several folks shared posts from one obvious grand juror who supported Democrats prior to now.

Jon B. Gould, a lawyer and criminologist on the University of California, Irvine, mentioned Georgia was pretty uncommon in making grand jurors’ names public. It opens up the chance that they could possibly be harassed for his or her selections, he mentioned, particularly in instances involving gangs and arranged crime.

Diane Peress, a former state and federal prosecutor who teaches at John Jay College of Criminal Justice, mentioned prosecutors in New York State and the federal system took pains to maintain the names of grand jurors secret. For occasion, jurors are often referred to solely by quantity throughout grand jury proceedings in New York State.

One motive for the Georgia rule requiring the discharge of the jurors’ names, mentioned Michael Mears, a professor at John Marshall Law School in Atlanta, is to present protection legal professionals a tiny window into the proceedings — letting them test, as an illustration, whether or not any of the jurors ought to have been excluded as a result of they have been convicted felons or resided exterior the county.

Aside from the names, procedures in Georgia are extra secretive than in New York, the opposite state jurisdiction the place Mr. Trump has been charged with crimes. New York retains a report of grand jury proceedings and testimony, which is turned over to the protection and can be utilized at trial.

But in Georgia, information will not be saved neither is a transcript made, Mr. Mears mentioned, making it extraordinarily troublesome to problem the grand jury’s resolution.
