Mark Sebastian, 46, faces multiple gun charges in connection what authorities said was the exchange of guns to settle a drug debt. Sebastian is the vice-chairman of the North Stonington-based tribe. Sebastian was arraigned Tuesday in New London court where he entered a not guilty plea to three counts of illegal transfer of a pistol or revolver and three counts of purchasing a firearm with intent to transfer it to a person prohibited from possessing a gun. All of the charges are felonies.
In 2005, authorities said Sebastian purchased three handguns for his cousin, convicted felon Calvin Sebastian, according to the arrest warrant affidavit prepared by a special agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives. Mark Sebastian owed his cousin $1,000 for cocaine, police said.
Calvin Sebastian, 37, authorities said, later traded two of the guns to satisfy his own drug debt.The arrest was the result of an investigation by the ATF, Drug Enforcement Administration and Norwich, Groton and New London police departments.
Held on a $250,000 bond, Sebastian is due back in court on Sept. 11.
