Sheriff’s Office SWAT team and bomb squad operators donned in Hazmat suits raided a Pearl River trailer Tuesday night, discovering pipe bombs and a suspected methamphetamine lab, authorities said.

During a search warrant, Claude “Lee” Smith, 35, was arrested in the trailer he lived in that is in front of a home at 36441 Ed Yates Road in Pearl River, Sheriff’s Office Capt. George Bonnett said.

“At this point we don’t belive the owners knew about the lab,” Bonnett said. The raid was the result of a traffic stop earlier in the week in which deputies “found something on Smith and it mushroomed,” Bonnett said. He did not clarify what deputies found.

Smith was wanted on two counts for failure to appear in court on marijuana and traffic charges, Bonnett said.

During the raid investigators found five pipe bombs and pistol with its serial number shaved off, he said. Outside was a pickup truck, also with its vehicle identification number removed. Detectives are investigating whether or not the pickup truck is stolen.

Investigators sent material inside the lab for analysis, but suspect the residue found inside is methamphetamine, Bonnett said.

“It was not an active lab, but it did look like it had been used in the last week or so,” Bonnett said.

Smith was arrested for removal of a VIN number, manufacturing of an explosive device and possession of a firearm with an obliterated serial number.

He was also arrested and booked with driving under a suspended license and the two warrants failure to appear in court, Bonnett said.

Smith is being held in St. Tammany Parish Jail in lieu of $190,000 bond.

The lab, an average size, is the first to be found in St. Tammany in about eight months, when two meth lab operators burned themselves during the manufacturing process and drove to Slidell Memorial Hospital for treatment, Bonnett said.

“Meth labs are not something we come across every week,” Bonnett said. “They are more commonly found in rural areas.”

Many meth lab operators operate clandestine mobile labs, where household materials are trucked around in a vehicle and set up at random remote locations for cooking the product, he said.
