Four people are facing felony drug charges in connection with an alleged heroin distribution ring in northern Vermont. The Vermont Drug Task Force Police said two men and two women were arrested Friday in connection with the June 6 seizure of 540 bags of heroin police say were being brought from southern New England to Vermont to be distributed. Deborah Clark, 53, of St. Johnsbury; Dillon Garand, 27, of Barnet; Kevin Palmer, 53, of Lyndon; and Clark’s daughter, Brittany Clark, 24, of St. Johnsbury, pleaded not guilty to the charges Friday in Caledonia Superior Court in St. Johnsbury. The Caledonian-Record reported that police allege that Deborah Clark was selling heroin out of her St. Johnsbury apartment that was brought into the state from Connecticut and Massachusetts. Police said they found the heroin in a vehicle driven by Garand.
