A man who served 17 years in prison for two murders he didn't commit has been sentenced to a year back in jail for retail theft.

On Tuesday, Anthony Porter pleaded guilty to retail theft for stealing deodorant from a South Side Walgreen's drugstore, CBS Chicago reports. Porter was charged in September 2011.

A warrant was issued for his arrest after Porter failed to appear in court July 2, state's attorney's office spokesman Andy Conklin told the Chicago Sun-Times.

Judge Diane Cannon sentenced Porter to a year in prison, but he was given credit for 60 days served in Cook County Jail, according to the Sacramento Bee.

Porter was first incarcerated in 1982 after he was convicted of murdering a teenage couple in Chicago. In 1999 he was released after Northwestern University's Medill Innocence Project, led by then-professor David Protess, obtained a confession from another man while investigating the case.
