Federal prosecutors returned to a grand jury in Greeneville on Tuesday and obtained a superseding indictment that doubles the amount of participants in an allegedly crystal meth-distribution conspiracy allegedly headed by Hamblen County residents Trinidad Balderas Jr. and Tawauna Boutwell, according to court documents.

The additions are Emanuel Haygood and Charles Slater.

Of the two, Haygood, 31, appears to be the higher-value target.

As part of the indictment, Assistant U.S. Attorney Rob Reeves filed notice that he plans to seek enhanced penalties for Haygood.

In 2006, Haygood was sentenced to five years in federal prison after he was convicted of selling crack cocaine.

Haygood has also been convicted in Hamblen County Criminal Court for selling methamphetamine, and has a pending meth-related case. Haygood was a “mid-level dealer,” who allegedly ounces of Mexican cartel-manufactured, according to Lt. Gene Watson, who leads narcotics investigations for the Hamblen County Sheriff’s Department.

Slater, a 64-year-old man who gave a Florida address, allegedly was holding more than an ounce of crystal meth when he was taken into custody by Deputy David Barker in May for a minor traffic infraction.

The conspiracy leaders, Balderas, 34, and Boutwell, 36, were indicted previously for conspiracy to distribute more than 500 grams of crystal meth, and authorities appear to have a dead-lock case on them.

Balderas and Boutwell, both convicted felons, allegedly were holding 1.4 pounds of methamphetamine when Hamblen County authorities executed a search warrant at their White Oak Church Road home in August.

When Reeves first presented the case to the grand jury, he disregarded 3.2 ounces of heroin, 30 pounds of marijuana, 28 Ecstasy pills, 1.1 ounces of powder cocaine and 2 ounces of marijuana also seized in the raid.

Also confiscated was nearly $24,000 in cash and firearms, three of which had been reported stolen. Balderas was re-indicted Tuesday for possession of a firearm in furtherance of a drug-trafficking offense.

In another case that involved a large amount of cash, Morristown resident Allan Russell was indicted Tuesday for conspiracy to distribute marijuana and possession of a firearm during a drug-trafficking offense.

Russell, 20, allegedly had nearly $60,000 in cash – in his vehicle and in his Valley Street residence – when he was arrested by the Morristown Police Department.

Police also confiscated nearly 2 pounds of marijuana and an AR-15 rifle, according to Detective Dustin Jones.

Officer Travis Mikels stopped Russell’s vehicle for speeding on Highway 25-E.
