Nurse Practitioner Convicted of Prescribing Nearly 1 Million Opioid Pills

A federal jury has convicted a Murfreesboro, Tennessee nurse practitioner of illegally distributing nearly 1 million opioid pills to patients, officials announced Tuesday. The conviction is one of the largest opioid-distribution cases ever tied to a single mid-level provider in the state.

According to the U.S. Department of Justice, 43-year-old Heather Marks, an advanced registered nurse practitioner, prescribed controlled substances to patients seeking pain treatment at the Lifeforce Pain and Wellness clinic in Carthage, TN. The conviction comes years after Marks was indicted in 2019 alongside other medical professionals in what authorities described as a major regional drug round-up.

From September 2016 through May 2018, federal prosecutors say Marks and other medical professionals overprescribed highly addictive opioids, including oxycodone and oxymorphone, to Lifeforce patients. According to the DOJ, evidence at trial showed Marks prescribed nearly one million opioid pills to almost 1,000 patients over the course of the conspiracy.

The patients were often addicted to illegal drugs and to the opioids that Marks and others prescribed, prosecutors said. “Marks ignored obvious signs of Lifeforce patients taking illegal drugs at the time she prescribed them opioids, which put these patients in danger of overdosing,” the DOJ stated. “Marks further prescribed opioids to Lifeforce patients who she knew were likely selling the opioids on the street.”

The Verdict and What Comes Next

On Monday, a federal jury convicted Marks of conspiracy to illegally distribute controlled substances and eight counts of illegally distributing controlled substances, according to WSMV. She is scheduled to be sentenced on Sept. 1, 2026, and faces a maximum penalty of 20 years in prison on each count of conviction. The charges were proven to a jury, though Marks has not yet been sentenced and her clinic codefendants’ cases have been resolved separately.

The case was investigated by the FBI, the U.S. Department of Health and Human Services Office of Inspector General, and the Tennessee Bureau of Investigation. It was prosecuted by Assistant Chief Jim Hayes and Trial Attorneys Lauren Randell and Manu Sebastian of the Criminal Division’s Fraud Section. Marks was originally charged as part of a sweeping federal effort targeting opioid prescribing in the region, an effort that charged dozens of doctors and nurses across multiple states.

This case matters deeply to the nursing profession because the defendant is a nurse practitioner, not a physician. Advanced practice nurses hold prescriptive authority for controlled substances, and that authority carries the same federal scrutiny that physicians face under the Controlled Substances Act. A conviction does not just end a career, it can mean decades in prison.

The allegations center on red flags that clinicians are trained to watch for: signs of active illicit drug use, patterns suggesting diversion, and prescribing volumes that fall outside legitimate medical practice. For NPs working in pain management or any high-volume prescribing setting, documentation, prescription drug monitoring program checks, and a willingness to say “no” are not just best practices, they are legal protection. When a provider’s prescribing pattern becomes the evidence in a federal trial, thorough charting and adherence to clinic protocols can be the difference between defensible care and a criminal charge.

Working inside a clinic does not protect an individual provider from accountability. Marks was held personally accountable for every prescription she signed, no matter who owned the clinic or what pressure she faced to keep patients coming through the door.
