The west central drug task force says this woman, Pa Xiong, was the ringleader. She's been indicted by a federal grand jury.
It took time; this was a year-long investigation and as a result, 20 people now face charges.
"This has severely diminished the availability of methamphetamine in our area," said Chief Deputy Matt Rokus of the Eau Claire Police Department.
Authorities call it the largest meth bust they've ever made, but it started off slowly.
"We would do one interview here, on one date, and then two months later we would do an interview over here. And then we would determine that there was a link," added Rokus.
It also started on a small scale, officers first catching a low-level offender.
"From that low-level drug transaction, we were able to leverage information which brought us into an intermediary drug dealer. From there, we were able to progress into the upper end of the conspiracy," Rokus said.
Authorities say the primary provider of meth to the Chippewa Valley was a woman named pa Xiong. They claim she brought twenty pounds of meth into the Chippewa Valley during the year long investigation. That amount comes with a street value in the tens of thousands of dollars.
"Methamphetamine is a highly addictive, very dangerous drug. It destroys people's lives. It leads to other criminal activity, sometimes violent crimes," said Rokus.
Xiong has been indicted by a federal grand jury. Two others, Lang Thao and Kyrie Tetzlaff, were also indicted by a federal grand jury for their alleged role. In total, 20 people face charges.
"The people charged in this investigation are a very small segment of our community. Unfortunately because of their addiction to methamphetamine, they commit a very high proportion of the amount of crime and disorder that's been impacting our region. Things like child neglect, child mistreatment. Others its fraud, theft, burglary,” Rokus explained.
The West Central Drug Task Force says other arrests are expected. But for now, they're happy with what's been accomplished.
"It is very important. Drug trafficking and drug use are very serious matters. By holding these drug dealers accountable for their actions; we are making Eau Claire and our region a much safer place," said Rokus.
At this time all three suspects indicted by a federal grand jury are being held in the Dane County jail. The seventeen others will be prosecuted locally. In addition to Eau Claire and Chippewa County, suspects could face charges in Dunn, Polk, and St. Croix Counties.
