Oakland County Sheriff Michael Bouchard says releasing more than 200 prisoners from the overcrowded County Jail could have been avoided, if judges had used alternative sentencing.
He tells The Detroit News he sent a letter to judges earlier this month, notifying them of the "jail emergency and asking for cooperation to help avoid it."
Michigan law requires sentence reductions if prisoners don't pose a high risk.
Bouchard says beds are being used by inmates who don't need to be in jail, and could have been punished differently, avoiding the problem.
