Wallace Stogner of Bogalusa, along with two others, pleaded guilty Wednesday to charges of distributing oxycodone pills. Oxycodone is a Schedule II controlled substance and available by prescription only.

Danielle Meisner, 31, of Mandeville, and Karen Smith, 57, of Slidell, also pleaded guilty.

The three have not been sentenced, but Stogner faces up to 20 years in prison for his role in the operation. The three defendants are scheduled to be sentenced before U.S. District Judge Kurt D. Engelhardt on Nov. 9.

The charges stem from a 2011 drug investigation.

In December 2011, Drug Enforcement Administration agents begin looking into illegal street sales in Bogalusa of Roxicodone, a drug that contains oxycodone. Oxycodone is a pain medication, and its effects are similar to heroin.

According to court documents filed in relation to the Stogner case, the Roxicodone pills were being sold in Bogalusa for $25 to $30 per tablet. The court documents state that the pills were coming from an unregistered pain management clinic, referred to only as Clinic A.

The clinic would change locations repeatedly, moving from New Orleans to Kiln, Miss., and would never post signs or advertising of any sort of medical practice. The DEA investigation discovered that anybody who went to the clinic for pain would come away with a prescription for a “high number” of Roxicodone tablets. The clinic didn’t take insurance, worked in cash only and charged $280 to $300 per visit. Sometimes a doctor was present at the clinic, other times not, but patients got prescriptions from staff regardless.

On Sept. 18, 2012, undercover DEA agents reportedly purchased Roxicodone pills from Stogner and Walker. Walker was a patient of the clinic.

At the purchase, Walker and Stogner had 81 pills present, and they were prepared to sell them for $2,125. The DEA agent didn’t have any small bills and Walker and Stogner couldn’t break a $100 bill, so the agent only paid the duo $2,100, agreeing to pay the remaining $25 later.

According to court documents, the undercover agent said he wanted more pills, and Walker said she’d go back to the clinic for more and they arranged to meet up again on Oct. 15, 2012. On that date, the agent met with Stogner and Walker and the two sold the agent 100 pills and Walker reminded the agent he still owed them $25 from the last drug sale. The agent handed Stogner $2,525 in exchange for the pills.

The pair were arrested after that sale.
