VINITA A Vinita doctor prescribed more than 1,000 Demerol and OxyContin pills to a nursing instructor who died with toxic amounts of painkillers in her system, the state attorney general alleges.

The complaint was filed Aug. 13 with the state Board of Medical Licensure and Supervision against Dr. Mickey Ray Tyrrell.

Tyrrell, 37, is accused of prescribing excessive amounts of narcotics to Tammy Dawn Daniels, 35, of Vinita.

Daniels, a nursing instructor at Northeast Technology Center in Pryor, died Sept. 5, 2009, from acute combined drug toxicity from forms of the painkiller Demerol, according to an autopsy report released by the state medical examiner's office.

A spokeswoman for the attorney general's office referred questions to the state medical board. Tyrrell's hearing before the board is set for Nov. 4.

Daniels' family couldn't be reached for comment this week.

She was hired Aug. 16, 2007, and still was working at the technology center's Pryor campus at the time of her death. She was a model employee, and nothing unusual was noted in her performance, said Jeanie Fox, an administrative assistant.

Craig County District Attorney Gene Haynes said there is an ongoing criminal investigation but declined to elaborate.

Tyrrell, a general practitioner with Green Country Family Medicine in Vinita, declined to comment on the allegations. He is co-owner of the clinic with another Vinita physician, his staff confirmed.

Tyrrell graduated in June 2002 from St. George's University School of Medicine in Grenada, and his license with the American Board of Family Medicine expires June 1, according to the state medical board.

According to the complaint, pharmacy records from June 2 through Sept. 2, 2009, show Tyrrell prescribed 990 Demerol pills (50 milligram) and 120 OxyContin pills (20 milligram) to Daniels. Records show Tyrrell noted only two prescriptions for Demerol in Daniels' chart, when he had written nine prescriptions, the complaint states.

The first notation made in Daniels' chart was July 29, 2009, and by that time, Tyrrell had written four prescriptions. The second reference was on Aug. 25, 2009. The remaining seven Demerol prescriptions were not reflected anywhere in the patient's chart, the complaint states.

Tyrrell told investigators he authorized the prescriptions but had no explanations as to why he documented only two of the nine.

"At the time of her death, the patient's body had multiple visible injection sites," according to the complaint. The complaint did not elaborate on how Daniels might have injected Demerol when it was prescribed to her in pill form.

In the last 35 days of Daniels' life, she received 630 Demerol pills and 60 OxyContin pills, an average of 18.5 dosage units per day of Demerol, the complaint states.

Complaint also states

Daniels was being treated by a Tulsa urologist for interstitial cystitis a recurring pain in the bladder and pelvic region when she started seeing Tyrrell for pain management. She asked Tyrrell for Demerol, which she told him she was taking already.

Tyrrell failed to obtain Daniels' medical records from the urologist to confirm what drugs she had been prescribed but immediately started prescribing Demerol and OxyContin. The medical records showed the urologist hadn't prescribed Demerol for more than three years.
