DETROIT (WWJ) - Kwame Kilpatrick has lost his latest bid to get out of prison.

A court filing shows a federal judge on Tuesday denied a motion by the incarcerated former Detroit mayor to vacate his 28-year prison sentence.

In explaining her decision, Judge Nancy Edmunds -- the same judge who sentenced Kilpatrick in 2013 -- said that the 48-year-old has not been able to "show actual innocence."

"As this court has previously discussed at length, the evidence at trial weighed heavily in support of the verdicts of guilt against Defendant," Edmunds wrote in her order.

The disgraced ex-mayor in 2016 and 2017 filed motions asking that his conviction be thrown out, alleging that impermissible hearsay allowed during testimony, incorrect jury instructions and a conflict of interest by his attorney, as well as other purported court errors.

The Sixth U.S Circuit Court of Appeals previously rejected his appeal, as did the U.S. Supreme Court in 2016.

First elected mayor in 2001, Kilpatrick​ resigned in 2008 after pleading guilty to perjury in a sex and text messaging case involving his Chief of Staff. In October of 2013, he was ordered to spend 28 years behind bars for convictions on 24 counts -- including racketeering extortion and bribery -- for fixing city business to enrich himself and his friends.

Kilpatrick's expected release date remains Aug. 1, 2037.
