The Department of Correction says Tackman has a history of escape attempts and a criminal record dating back to 1978.
Tackman had been wearing a business suit when a court officer spotted him on Wednesday and mistook him for an attorney.
Tackman was a defendant on trial on a second-degree robbery charge.
Despite the efforts of a swift mobilization, the sealing of the Criminal Courthouse building, and the dogs of both the Corrections Department and NYPD K-9 units picking up and following the prisoner's scent, Tackman remained at large
Tackman pulled off his daring escape by walking out of an unlocked State Supreme Court prisoner holding area on the 12th floor of 100 Centre Street.
He strolled through an 11th-floor courtroom, where a court officer apparently mistook him for a lawyer and called him counselor, but didn't stop him. The felon, who should have been treated like a flight risk, walked right out of the north entrance.
Authorities say Tackman visited his mother shortly after his escape, where he changed clothes and then left.
Tackman's mother, Gene Devine, said that her son came home "all dressed up." She says she figured he'd been discharged from prison. He changed clothes before leaving.
Tackman's prison record has him in Sing Sing in 1978 for an attempted robbery, at Rikers three years after that and in Attica in 1984 for another robbery and escaping custody..

Tackman's arrest record, according to state department of corrections:
The 1985 escape from custody involved Tackman taking over a prison van as it crossed the Brooklyn Bridge into Manhattan, headed to court. He fired a pellet gun at corrections officers but missed.
He also had a previous escape attempt, when he briefly took over a prison van with a gun made out of soap.
