A hearing on whether a reporter should be ordered to testify about how she obtained confidential information in the Colorado theater shooting case is being continued until next week.

New York-based Fox News reporter Jana Winter cited anonymous law enforcement officials in reporting that suspect James Holmes had sent a psychiatrist a notebook of drawings that foreshadowed the July 20 attack.

Prosecutors and Holmes’ lawyers argued about the issue in court Monday, but the defense wants to again question a detective about whether he might have told someone else about the notebook, who may have then talked to Winter.

The judge agreed and scheduled another hearing for April 10. He raised the possibility that Winter’s source was from outside Colorado, and not subject to the case’s gag order.
