HARTFORD — One of the last defendants in the 1983 robbery of $7 million from an armored car depot pleaded guilty Friday to his role in the record-setting heist, accepting a deal that calls for him to serve five years in prison.
Norberto Gonzalez Claudio, who was captured by the FBI last year in Puerto Rico, had been one of two remaining fugitives in the crime carried out by Los Macheteros, a militant group dedicated to independence for the US Caribbean territory.
Wearing a gray beard and a beige prison jumpsuit, the 67-year-old Gonzalez acknowledged in US District Court that he was a member of the organizing committee that planned the heist and arranged for the money to be sent out of the US mainland to Mexico.
Authorities have said they believe the money was used to support the clandestine group’s operations.
Gonzalez pleaded guilty to two charges from the original indictment — foreign transportation of stolen money and conspiracy to rob federally insured bank funds — as well as a new charge of illegal weapons possession related to an automatic pistol found in his home when he was arrested. The plea agreement calls for capping his sentence at five years, and he will receive credit for the time he has spent in custody.
Gonzalez offered only brief responses to the judge’s questions. Hilton Fernandez, a supporter who also served prison time for the robbery, said Gonzalez planned to make a political statement at the sentencing, which was scheduled for Sept. 27.
Gonzalez’s wife, Elda Santiago, was allowed to speak with him briefly before marshals escorted him away in handcuffs.
‘‘I think he is very happy that this part of the process is ending and he can go through his sentence and come back,’’ she told reporters outside the courthouse.
An older brother, Avelino, was sentenced in 2010 to seven years in prison after spending more than two decades as a fugitive for his role in the heist. A third brother, Orlando, was also convicted of taking part in the robbery and has since been released.
‘‘We are proud of Norberto for being a fighter,’’ Orlando Gonzalez said outside the courthouse. ‘‘He is a fighter for the independence of Puerto Rico.’’
Norberto Gonzalez has been detained since he was arrested in May 2011 in the central island town of Cayey, where he had been living under a false name.
US authorities said he still had an active role in the Macheteros, which claimed responsibility for robberies, murders, and bombings in the 1970s and ’80s.
The brazen holdup of the Wells Fargo depot on Sept. 12, 1983, in West Hartford, Conn., was the largest cash robbery in US history at the time.
