Jason Dale Woolery, 29, of Spencer, and Christina Marie Thong, 22, also of Spencer, were arrested at a methamphetamine (meth) lab that was found northeast of Spencer.
Both were charged with possession of meth precursors, a class D felony, and manufacturing of meth, a class C felony. A $42,250 bond has been set for both Woolery and Thong. Both are being held in the Clay County Jail. Other charges and arrests are pending.
On Wednesday, at 11:45 a.m., the Clay County Sheriff's Office received a complaint about a possible meth-amphetamine lab dump site northeast of Spencer. When deputies arrived at the scene, they found a five-gallon bucket containing coffee filters, which are used in the manufacturing of meth.
After inspecting several buildings on the property, it was determined that this was an active meth lab in operation.
State agents, who have a lab team of agents, were then contacted to investigate the meth labs and dump sites.
Assisting the Clay County Sheriff's Office with the call was the Spencer Police Department, the Iowa State Patrol and state and federal agents.
According to the sheriff's department, the coffee filters found at the site are just one of a number of items that are usually found at meth lab operations and dump sites. The coffee filters are used to strain ephidrene, a key ingredient in meth.
Other items that are usually found at meth labs and dump sites include muratic acid jugs, ether cans, one gallon gas cans, starting fluid, funnels, coffee cans and hoses.
