A St. Joseph man has been sentenced to serve 16 years behind bars after robbing a cell-phone store earlier this year on S. Belt highway.

Isaiah Williams pleaded guilty in February to a felony of first-degree robbery.

As we previously reported, Williams and co-defendant Shania Harness were accused of robbing the  Metro PCS cell-phone store at gunpoint in January.

Buchanan County Judge Daniel Kellog sentenced Williams on Thursday to serve 16 years for the crime.

Harness also pleaded guilty to a felony of first-degree robbery in March. Sentencing for Harness is scheduled for next week.
