(Minneapolis, MN) -- Derek Chauvin is guilty on all counts in the death of George Floyd, but it's not known how much time he will spend in prison. The second-degree murder charge carries a maximum sentence of 40 years in prison. Third-degree murder carries a maximum sentence of 25 years and the manslaughter charge carries a top sentence of ten years. However, Minnesota sentencing guidelines say someone with no prior conviction like Chauvin could be sentenced to 12-and-a-half years for all the murder charges. The sentencing is up to the judge and he could hand down concurrent sentences, instead of multiple consecutive sentences, because all three charges are related to the same crime. If that happens, Chauvin could be out of prison in about 12-and-a-half years.
