The Supreme Court will not stop subpoenas issued to an advocate for chronic pain patients who is under investigation for obstruction of justice.

Siobhan Reynolds and her organization, the Pain Relief Network, are being investigated because of her involvement with a doctor and wife who illegally prescribed painkillers to dozens of patients who later died.

The high court on Monday refused to hear an appeal from Reynolds.

Reynolds wanted justices to quash grand jury subpoenas and her contempt citation for not turning over subpoenaed e-mails and documents.

The court filings in Reynolds' case have been sealed.
