MAQUOKETA, Iowa (AP) -

An Iowa man sentenced as a teenager to life behind bars for a 1984 killing is now eligible for parole.

The Dubuque Telegraph Herald reports that 47-year-old Mitchell Ronek has spent nearly 30 years in prison for the death of Thomas Goodwin, of Maquoketa. Ronek was 17 at the time of the killing.

During a resentencing hearing Friday, Judge Mark Smith sentenced Ronek to life in prison with parole with a minimum of 25 years in prison and credit for time served.

Ronek's resentencing following a 2012 U.S. Supreme Court ruling that said it is unconstitutional to sentence teenagers to life without the chance of parole.

Ronek's new sentence will now go to the Iowa Board of Parole, which will decide whether Ronek will be released.
