( CNN ) -- A couple convicted of tax evasion was taken into custody after a five-month-long standoff with federal agents in New Hampshire , a federal law enforcement source with knowledge of the investigation told CNN . Ed and Elaine Brown , who had refused to surrender to authorities to serve their prison sentences , were taken into custody without incident Thursday evening by U.S . Marshals at about 8:00 p.m . The Browns had been holed up in their concrete-reinforced home in Plainfield , New Hampshire . They were convicted of evading $ 1.9 million in taxes -- a crime punishable by up to five years in prison . The Browns were sentenced in absentia in April . Throughout the ordeal , the Browns insisted there was no valid law that requires them to pay income taxes . `` We have committed no crime and we will not go to prison for non-crimes , '' Elaine Brown told CNN in June . Marshals cut off utilities to the house in early June , but the Browns told CNN it was not much of a hardship because they had their own wind turbine , as well as solar panels that provided some electricity . Also , their property covers more than 103 acres , so there was plenty of wood to keep them warm in the winter , they said . The couple and their New Hampshire home had become a rallying spot for anti-government supporters . Randy Weaver -- a survivor of the 1992 incident in Ruby Ridge , Idaho -- had recently visited the Browns to show his support . Over the summer , the Browns invited their supporters and friends to an outdoor party on their property that included live music , bocci and barbeque . Their online invitations asked attendees to `` stand in solidarity with the Browns against income tax fraud and celebrate freedom . '' U.S . Marshal Steve Monier told CNN the service had no desire to engage in a violent confrontation with the Browns . `` But warrants are n't going away . They will serve their prison sentence , '' he added . The Browns , who are in their 60s , now likely face a host of other charges . They accumulated the back taxes between 1996 and 2003 , in part from money made from Elaine 's private dental practice . Four people accused of aiding and abetting the Browns , including one man who allegedly provided security , were arrested and taken into custody in mid-September . E-mail to a friend .
