Two Davenport residents are facing charges of methamphetamine trafficking after a traffic stop Thursday night led to a broader investigation and their arrest Friday.

According to Davenport Police Capt. Dale Sievert, at 10:15 p.m. Thursday, an Iowa State Patrol trooper stopped a vehicle on U.S. 61, or 140th Street, near the intersection of Y48, or 110th Avenue, in Scott County west of Davenport.

The trooper discovered that the vehicle contained materials consistent with the manufacture of methamphetamine.

Agents with the Iowa Department of Narcotics Enforcement, or DNE, were called to the scene, as were members of Davenport’s Tactical Operations Bureau.

The investigation grew to include the Quad-City Metropolitan Enforcement Group and the Bettendorf Police Department.

The investigation led police to several addresses in Davenport and Bettendorf that were searched and where items involved in methamphetamine production were seized.

At 9:09 a.m. Friday, Davenport Police and DNE agents were sent to 3831 Bridge Ave. regarding the methamphetamine investigation.

There they found a van registered to Joseph Allen Terry, 36, who also had a passenger in the van, Felina Danielle Lochner, 35. Both live at 2112 N. Clark St., Davenport.

According to the arrest affidavit filed by Davenport Police Sgt. Brad Jensen, a hypodermic needle with suspected methamphetamine was located on Lochner.

In the van, officers seized two vessels containing sludge and solvent in which were more than 5 grams of detectible methamphetamine, according to Jensen’s affidavit. Also found in the van were empty pseudoephedrine packs, lithium batteries that had been cut open, coffee filters, lye, plastic tubing and camp stove fuel.

Lochner and Terry were arrested. Each is charged with one count of drug possession and delivery for the methamphetamine.

The two were being held in the Scott County Jail on $100,000 bond each.

Drug possession and delivery as it relates to methamphetamine is a Class B felony under Iowa law that carries a prison sentence of up to 25 years.
