SPRINGFIELD, Mo. - The U.S Marshals want to turn up the heat on a cold case of a convicted felon who went underground more than five years ago.

Larry Allen Chamberlin, 56, was convicted in the U.S. Federal Court District of Kansas for selling firearms without a license in 1980. A year later, he was convicted in Missouri for several counts of burglary and stealing.

Deputy U.S. Marshal Darren Lane says after 1981, Larry Chamberlin fell off the radar, until he went to a garage sale in 2006. "In 2006, he went to a garage sale in Republic, Missouri. and while at the garage sale he asked to purchase a firearm." An off-duty police officer happened to overhear Chamberlin's request and discovered he was a convicted felon.

That officer told federal officers with the Bureau of Alcohol Tobacco, Firearms and Explosives. Investigators served a search warrant and found 14 firearms, ammunition and several Marijuana plants. Federal prosecutors charged Chamberlin with being a felon in possession of firearms for manufacturing marijuana.

Lane says investigators also discovered Chamberlin "had a reputation for being a notorious poacher and found fox tails, bobcat pelts and other things that indicate that there might have been some Missouri Wildlife violations as well."

Chamberlin only showed up to a few court hearings in 2006 before officers say he disappeared.

Chamberlin has ties to Kansas, Nevada in Southwest Missouri, and lived in Nowatta County north of Kansas City.

Marshals say Chamberlin advertised himself as a wildlife outfitter, and rented property which he would re-lease to other on which to hunt.

Lane says Chamberlin is known to be armed and dangerous, "In Mr. Chamberlin's case, he's made statements in the past that no one will restrict his access to firearms or restrict his access to hunting."

Chamberlin is 56-years old, is 5'8", weighs 230 pounds, and has gray hair with hazel eyes.  If you know where he is, call the U.S. Marshals at (417) 831-0588.
