In addition to immigration violations, federal prosecutors charged him with having illegal weapons.
Property records indicate that someone using the name Michael Maher lived in New Hampshire, mainly in Concord, from 1997 until 2006. He was also connected with homes in Florida, Wisconsin and Minnesota.
Maher made an initial appearance Thursday in federal court in Springfield and asked for a court-appointed attorney because he didn't have enough money to pay for representation.
Dressed in blue jeans and a gray polo shirt, with closely cropped salt-and-pepper hair, Maher appeared calm and respectful during the two-minute hearing. He is in the custody of U.S. marshals and was scheduled for a preliminary hearing Feb. 22.
After being taken into custody, Maher told an FBI agent he had been using his brother's name since 1998, when he began working in the U.S. He said he obtained a Social Security number under that name.
Brett told agents her husband also sometimes used name Stephen King.
In Ozark, Maher had been a cable installer for St. Louis-based Suddenlink Communications.
Pete Abel, the company's senior vice president of corporate communications, acknowledged Maher was an employee but declined to go into details about his duties or how long he had worked there. Before he was hired, managers conducted a background check, which found no evidence of a criminal past, Abel said.
Ozark Police Chief Lyle Hodges praised one of his officers for his persistence after getting the initial tip that Maher was a fugitive. Officer David Overcast did research that revealed the armored car robbery and found a photo of Maher, Hodges said.
Because there were no active warrants, the chief said, "it is entirely possible that another officer might have stopped investigating."
