While the FBI managed to arrest dozens of people connected with the crime, include tow of Gonzalez Claudio's brothers, they never managed to find him. So as his sibling served seven years behind bars, he lived a life on the lam.
But now it looks like he'll have to spend his twilight years in prison for his role in the robbery as he faces 275 years if convicted.
A federal arrest warrant issued in 1985 charged the Puerto Rico native with obstruction of commerce by robbery and conspiracy.
He is also believed to be a member of Los Macheteros - or "The Machete Wielders" - a domestic terrorist organization whose goal is independence for the tiny island.
It's thought some of the money form this heist went to the group which has claimed responsibility for several murders, armed robberies and terrorist bombing in the name of it's cause.
