He served his time at a medium-security correctional facility in Sumterville, Fla., before being transferred to a nearby residential halfway house in mid-February.
His weeklong walkabout was not his first attempt to get out of prison: In late 2020, Mr. Taddeo applied for compassionate release because of concerns about contracting Covid in prison, a request that was denied by a federal judge, Frank P. Geraci Jr.
In his decision, the judge noted Mr. Taddeo’s lengthy criminal career, an unlawful path that began at the age of 16 and peaked, in horrific fashion, with the murders of three men and reputed mob associates — Nicholas Mastrodonato, Gerald Pelusio and Dino Tortatice — in 1982 and 1983.
Mr. Taddeo had also attempted to murder a mob leader, Thomas Marotta, shooting him on two separate occasions. The murders — and unsuccessful attempts — resulted in racketeering convictions in the early 1990s, and led to his stay in the federal prison system.
Last week’s escape was also not Mr. Taddeo’s first unauthorized jaunt: In 1987, Mr. Taddeo jumped bail, before being captured two years later. His suspected activities during that period were no less frightening: Federal authorities speculated at the time that Mr. Taddeo was involved in a plot to break a Colombian drug lord out of an Illinois prison.
