Two Warren County men were arrested and charged with possession of methamphetamine and attempting to manufacture the drug, according to the the Warren County Sheriff's Department. The men, Aaron E. Hausermann, 31 of the 1600 block of Concord Hill Road in Marthasville, and Lance M. Boeser, 34, of the 26000 block of Summerwind Drive in Warrenton, were arrested last week after an ongoing surveillance operation by detectives. Hausermann also was charged with one felony count of endangering the welfare of a child. No court date has been set for the suspects. They were arrested, charged and released after posting bonds of $60,000 for Hausermann and $25,000 for Boeser. Warren County Sheriff Kevin Harrison said his department had the men under surveillance for a period of four days. The operation took detectives through parts of Warren, Lincoln, Franklin and St. Charles counties. "During that time, we were able to follow the suspects to see where they went and who they had contact with," Harrison said. "During the course of our operation, we also observed one of the suspects attempting to dispose of the remains of a meth lab." Harrison said the surveillance resulted in the discovery of three meth labs, the seizure of two quantities of suspected meth and the arrests of seven people. The minor child, a 2-year-old female, also was taken into protective custody, a police report said. "We spent four days on this case, but it was time well spent," Harrison said. "The pieces all finally came together and we're very pleased with the results we had." What was unique, Harrison added, was that the operation was carried on primarily out of a house in the Concord Hill area. "That's not typically an area where you can usually expect to find this kind of activity," he reported. "It's pretty rural in southern Warren County where these two suspects were operating. "But I also think it points out that no area is safe or immune from the operation of a meth lab," Harrison said. Harrison said detectives had initially responded to complaints from nearby residents about suspicious activity. Once their surveillance began, they observed the use, sale and manufacture of methamphetamines from the residence, authorities allege. During the course of the investigation, detectives observed Boeser allegedly disposing of some items in a dumpster near Hatchery Road and Valley View Drive north of Concord Hill. Detectives determined the items were the remains of a meth lab, Harrison said. A search warrant was obtained for the residence. In addition to the suspected meth, detectives also recovered a small quantity of suspected marijuana and drug paraphernalia related to the manufacture of meth such as plastic containers, tubing, lithium batteries, foil, plastic bags, rubber gloves, filters, plates and camp fuel. Harrison said the investigation is "yet another example of private citizens working in conjunction with the sheriff's department to bring a successful conclusion to a criminal operation." Harrison said citizens often serve as the "eyes and ears" for police and can provide the first link to suspected illegal drug operations. "It illustrates what can happen when the public and our department work together," he said. "As we continue our ongoing investigations throughout the county, we depend on residents providing information which will tell us when something unusual is going on in neighborhoods. "You never know when information will be the first step or the final link in presenting a prosecutable drug case," he added. "Information from the public is a tremendous asset, no matter how insignificant it might seem." Harrison urged persons with knowledge or concerns regarding any illegal activity to call the sheriff's department at (636) 456-4332.
