Disgraced media mogul Conrad Black is expected to be released from a U.S. prison this week after serving about half of his 13-month sentence for fraud and obstruction of justice.

According to the Federal Bureau of Prisons' online inmate locator list, Black is scheduled to be released this Saturday from the Federal Correctional Institution in Miami.

The website lists May 5 as Black's "actual or projected" release date and reports have suggested he could be a free man as early as Friday. It's unclear where he will reside after he is released.

Black, 67, entered the low-security prison last September to serve out the remainder of his original six-and-a-half year sentence, handed down in 2007. He unsuccessfully appealed the fraud and obstruction of justice convictions, related to the sale of newspapers by his company at the time, Hollinger International Inc.

Black was released from another Florida prison in the summer of 2010 pending the appeal, which was denied last June. A Chicago judge gave him credit for time already served behind bars, but ruled that he must spend another 13 months in jail.

Black recently clinched a legal victory when the Supreme Court of Canada ruled that he may pursue a series of libel lawsuits in Ontario against his former Hollinger associates.

Black sued several people for comments he saw as defamatory. The remarks were published in the U.S. and then reprinted by media outlets in Canada.

The defendants took the case all the way to the Supreme Court, but it ruled that since Black first built his reputation and business in Ontario, he should be allowed to legally pursue the libel accusations in the province.
