A Searsport woman and two of her alleged co-conspirators are scheduled for trial at U.S. District Court in Bangor Tuesday, March 1.

Shannon Clark, 34, of Searsport, along with 30-year-old Vashti “Vash” Ramcharitar and 34-year-old Raymond “Andy” Romero, both of West Melbourne, Fla., are facing federal charges due to their alleged involvement in a scheme to mail prescription drugs from Florida to Maine.

According to court records, Clark, Romero and Ramcharitar were indicted in November by a federal grand jury on the charge of conspiracy to possess, with the intent to distribute, controlled substances.

Clark, who was arrested in Florida in November, pleaded not guilty to the charge and has since been free on personal recognizance bail, according to court documents.

U.S. District Court Magistrate Judge Margaret Kravchuk ordered Ramcharitar held without bail, while Romero had agreed to remain in custody pending the outcome of the case. Ramcharitar and Romero both pleaded not guilty to the charges against them in November.

Court records do not indicate the nature of the relationship between Clark and the Florida pair.

The investigation into the activities of the trio began in Waldo County in August of last year, according to court affidavits. An informant told a Maine Drug Enforcement Agent Ramcharitar was a native of the island of Trinidad, and she was residing at a home she owned in Florida with Romero.

The informant told MDEA agents he had been receiving packages in the mail from Ramcharitar and Romero for the past few months, and said the packages contained between 50 and 100 pills. The pills were identified in court records as the painkiller Percocet.

Court documents indicate the informant then agreed to help agents set up a controlled buy with Ramcharitar and Romero in September, and as part of the plan, U.S. Postal Inspection Service Inspector Troy Dumond set up a police-monitored post office box in Belfast for the purpose of receiving the package.

A package was received from Florida at the Belfast post office box Sept. 25, 2010, according to court records, and an MDEA inspection identified the contents as 100 30-milligram Roxicodone tablets and 55 20-mg oxycodone pills.

Ramcharitar, Romero and the informant appeared to be using a code in which they referred to the pills as prepaid calling cards, court documents reveal. For example, in a text message sent Sept. 22, 2010, the informant learned from Ramcharitar that Romero “is going to send 100 30 min cards and 55 20 min [cards].” When milligrams are substituted for minutes, the quantities of “cards” correlates directly to the quantities of pills that drug agents discovered in the package that arrived at the Belfast Post Office three days later.

Still using the references to cards, Ramcharitar reportedly sent a text message to the informant on Sept. 23, 2010 saying she had shipped them to him, and additionally discussing the pricing of the “cards.”

“The sender indicated that the ’20 min cards will be 12′ ($12.00) and ‘the 30 min ones are 14’ and added ‘We are getting 15 all day long down here. If I was u I would up them up there.’,” the affidavit states.

Court records do not indicate if the informant has been charged in connection with the alleged drug-mailing plot involving Clark, Ramcharitar and Romero, but they do state that the informant had previously “confessed to his involvement in trafficking oxycodone between Florida and Maine.”

Due to that reported confession, court paperwork states the informant has been told that he is “the target of a federal investigation,” and that he will “likely be charged with a federal offense.” It also notes that the prosecutor who handles any case involving the informant will be told of his cooperation with the case involving Clark, Ramcharitar and Romero.

If convicted, Clark, Ramcharitar and Romero could each face a penalty of up to 20 years in prison and a fine of up to $1 million.
