She was supposed to keep her mouth shut. Now, this Miami juror faces prison for blabbing

She was supposed to keep her mouth shut while serving secretly on a federal grand jury in Miami.

But then she blabbed about an indictment on Facebook to the girlfriend of a felon charged with illegally dealing firearms, even sending her photos of it.

Now, Leslie Lynn Heburn, 37, of Miami could go to prison for up to 10 years after pleading guilty Tuesday to an obstruction charge in the same federal court.

Heburn was sworn in as a federal grand juror in January of last year and was told about the jury's strict rules of secrecy, including never to disclose any matters, or she could be criminally charged herself.

On May 4, 2017, Heburn and the other grand jury members received copies of a proposed indictment of Rocky Dejesus Molina on charges of dealing firearms without a license and being a felon in possession of firearms and ammunition. The grand jury returned the indictment against Molina.

Jurors were told not to leave with any information from the grand jury room on the seventh floor of the federal courthouse on North Miami Avenue.

But a week later, before Molina's arrest, Heburn used an alias Facebook account and reached out to Molina's girlfriend via Facebook Messenger, according to court records. She told the girlfriend that she was serving on the grand jury and saw Molina's name on an indictment.

"Heburn then warned Molina's girlfriend that Molina had been set up by a 'snitch' since March 2016," federal prosecutors said.

After Molina was arrested on May 24, 2017, his girlfriend contacted Heburn on her alias Facebook account to ask more questions. And that is when Heburn sent the girlfriend photos of Molina's indictment. She continued to tell the girlfriend that Molina had been set up a number of times by a confidential informant deployed by the Bureau of Alcohol, Tobacco, Firearms and Explosives, according to records.

Heburn also told the girlfriend that she knew she could get into trouble for leaking information from the secret grand jury, prosecutors said.

After Molina pleaded guilty in October to firearms charges, he was sentenced to 15 years in prison. Heburn soon received a "target letter" from the U.S. Attorney's Office, accusing her of breaking the law as a grand juror.

In April, Heburn was charged with obstruction for "impeding a federal criminal investigation and prosecution" and contempt for having "disobeyed a lawful order" not to disclose secret grand jury information.

Heburn, represented by defense attorney Barry Wax, pleaded guilty Tuesday before U.S. District Judge Marcia Cooke. Her sentencing is set for Aug. 22.
