A Detroit-area woman who was removed from a jury for commenting about the ongoing case on Facebook has a longer writing task ahead: a five-page essay about the constitutional right to a fair trial.

A judge ordered the essay Thursday for Hadley Jons, three weeks after she wrote on Facebook that it was "gonna be fun to tell the defendant they're GUILTY." The trial, however, wasn't over.

"I'm sorry, very sorry," Ms. Jons, 20, of Warren told Macomb County Circuit Judge Diane Druzinski.

The post was discovered by the defense team Aug. 11 — before the defense had even started its case — and Ms. Jons was removed from the jury the next day.

Judge Druzinski told Ms. Jons that it didn't matter whether she used Facebook to express an opinion or simply spoke to a friend about the case.

"You violated your oath. ... You had decided she was already guilty without hearing the other side," the judge said.

By Oct. 1, Ms. Jons must submit an essay about the 6th Amendment to the U.S. Constitution and pay a $250 fine.
