NATCHEZ — The Natchez Police Department recovered Tuesday night crystal methamphetamine byproducts and manufacturing supplies on Highland Boulevard.

Natchez Lt. Craig Godbold said the department’s K-9 units recovered the byproducts, one-liter Coca-Cola bottles used to cook the meth, tubing and other meth-cooking supplies.

Metro Narcotics Major David Lindsey said the meth byproduct is called “sludge” and is what is leftover after meth is cooked.

Godbold and Lindsey said the items recovered indicate that someone was using a mobile lab to cook the meth using the “shake and bake” method.

To “shake and bake,” the household cleaning products and other meth-cooking supplies are placed in a bottle and shaken to cook the meth.

Lindsey said the suspects likely tossed out the sludge and materials once they made the meth.

The sludge is a biohazard and will disposed of by trained professionals, Lindsey said.

“We’re not qualified to dispose of it, so they will collect all of it and dispose of it,” he said.

The sludge is too hazardous, Lindsey said, to be of used for evidence.

Anyone with information about the meth should call Crime Stoppers at 601-442-5000.

Crime Stoppers offers a reward of up to $1,000 for a tip leading to the arrest and conviction of a suspect.
