Warren County Sheriff Kevin Harrison said drug criminals should be on notice. In what is being called Warren County's biggest drug roundup ever, law enforcement authorities from several agencies took 30 individuals into custody and were seeking to arrest 25 others following an extensive two-year undercover operation that culminated Thursday, Oct. 1. He said the suspects were involved in 105 criminal offenses. "One of the things we wanted to do was identify our more significant players and work up the chain," Harrison said. "That is why it took two years. For me, it was a chance to identify people buying quantities of drugs. It definitely is having a consequence out there. Hopefully it's a deterrent. We put a serious dent in our local drug action." Harrison said $14,392 was spent to purchase drugs during the undercover operation. He added that undercover officers were able to blend into the local drug scene and make numerous contacts to identify the drug users and dealers. The bulk of the arrests were made in Warren County, according to Harrison. Other individuals were arrested in St. Charles, Lincoln and St. Louis counties. Harrison said the suspects will be facing multiple felony charges for possession and drug trafficking along with other charges. He said the subjects' bonds ranged from $25,000 to $75,000. The remaining warrants will be served as the 25 subjects are located. The major drug sting follows another large roundup two years ago. Forty-five individuals were taken into custody in October 2007 for what was then the largest roundup in the county, according to Harrison. "Over the last two years, I've had people contact me and say this is going on," Harrison said. "I tell them we're working on it and to be patient. Sometimes I wish we could see immediate action. We wanted to find out who our players were." According to Harrison, authorities seized more than 5 pounds of marijuana, 17 grams of powder cocaine, 14.25 grams of crack cocaine, 31 bindles of heroin, 6 grams of hallucinogenic mushrooms, 1 gram of methamphetamine and more than 500 prescription medicine pills and "ecstacy." Also during the two-year investigation, authorities made 41 arrests, performed 25 controlled buys, seized 30 meth labs and confiscated 33 guns. "This was something we made the decision early on, to let it run and make as many cases as we can," Harrison said. "We are taking this seriously. This was a success for us. This is an ongoing cycle to keep repeating itself." As arrests were made Thursday, Harrison said officers confiscated eight marijuana plants at one residence and found 1.5 pounds of marijuana at another home. Harrison applauded the cooperation from the other agencies involved, including the Warrenton and Wright City police departments, East Central Drug Task Force, St. Charles County Sheriff's Department, Missouri State Highway Patrol, U.S. Drug Enforcement Administration, U.S. Bureau of Alcohol Tobacco and Firearms and the Lake Area Narcotics Enforcement Group. He said 40 officers were involved in the roundup. "We are very competitive with the different agencies, but in a matter like this everybody comes together," Harrison said. "That was a key to this success. For us, it's rewarding for local law enforcement to let people know their time has come and they have to answer to what they are doing."
