Investigators from the Drug Enforcement Agency and other law enforcement agencies served search warrants about 9 a.m. at the Wrens office and home of 69-year-old Dr. In Wahn Yun and at the next door pharmacy, Wrens Drug, where investigators say many of the prescriptions were filled. "Our primary target here is the doctor," Sheriff Gary Hutchins said Tuesday.
"We believe that the majority of the prescriptions were being filled next door, but we are not charging him (the pharmacist) with anything at this time."
The investigation, which began about four years ago but was taken on by the DEA only recently, started at the behest of local residents.
"They came to us because they were concerned about their family members who they claimed were going to Dr. Yun and getting prescriptions for drugs when they knew their loved one didn't need them," Sheriff Hutchins said.
Investigators refused to reveal what medications, other than hydrocodone, a pain reliever related to codeine, were involved.
Investigators spent much of Tuesday reviewing records at Dr. Yun's home and office and prescription records written by the doctor at the next-door pharmacy.
Dr. Yun has been charged with eight counts of distributing and dispersing a legal drug illegally. Each count is a felony and carries a possible five-year prison sentence and $25,000 in fines.
In all, Dr. Yun faces 40 years in prison and $200,000 in fines. He also will face charges of theft by receiving stolen property and possession of a weapon during the commission of a felony, both involving a pistol discovered during the searches.
"This investigation is ongoing, and we encourage anyone who wants to come forward with additional information they feel would be helpful," the sheriff said.
Sheriff Hutchins said Dr. Yun has practiced in Wrens for nearly 30 years.
