The U.S. Supreme Court decided not to hear Keith Kutska's appeal in his attempt to overturn his conviction of the 1992 murder of Tom Monfils, also known as the "Monfils 6" case.
Kutska and his attorneys filed a "petition for a writ of certiorari" in May asking for the U.S. Supreme Court to hear an appeal from a lower court.
The Supreme Court denied that petition Monday, October 2.
Kutska and five others, known as the "Monfils 6," were convicted of the 1992 murder of Tom Monfils, their co-worker at a Green Bay paper plant. His body was found in a paper vat.
Kutska is currently serving a life sentence.
Dale Basten, another one of the men convicted, was recently released from prison and placed in an assisted living facility due to his failing health.
Michael Piaskowski, another man convicted in the case, was released back in 2001 after a judge said there was not enough evidence against him.
The "Monfils 6" were all convicted in 1995. Four men now remain behind bars. One of them, Reynold Moore, is eligible for parole this year.
