ST. CLOUD -- Two men are jailed and two meth labs have been shut down following a five-month investigation into the manufacture of meth in the St. Cloud area.

Officials with the Central Minnesota Violent Offenders Task Force used a search warrant Tuesday to check out a van owned by a jailed meth manufacturer.

Recently, the van has been driven by another man, 62-year-old Derald Hausmann. Police impounded the van and searched it. Inside, police say an active meth lab was found in the back of the van, including chemicals used to make the drug and a 150 pound anhydrous ammonia tank.

On Wednesday, officers used a search warrant 1214 7th Avenue North and found additional ingredients used to make the drug and about two grams of finished product. Officers arrested 46-year-old Scott Olson at the home.

Another warrant was used at an apartment at 1215 East St. Germain Street. Police found Hausmann and another man there along with five grams of meth. Police jailed Hausmann on suspicion of first degree manufacture of methamphetamine in both Stearns and Benton Counties, possession of meth and illegal possession of anhydrous ammonia.
