Fox reporter Jana Winter back in court Monday over subpoena in Colorado theater shooting case

AURORA, Colo. - A Fox News reporter returns to court Monday for a hearing in the fight over the identity of her sources for a story about theater shooting suspect James Holmes.

Jana Winter is due in court so the judge can extend her subpoena. Without the extension, the subpoena would expire Monday.

Holmes is charged with killing 12 and injuring 70 in a movie theater in July 2012. His attorneys want to know who told Winter that before the shootings, Holmes sent a psychiatrist a notebook containing violent drawings.

The defense contends the leak violated a gag order. They also say police officers may have undermined their credibility as witnesses if they lied when they  denied being Winter's source.

Winter has said she won't identify her sources.
