Multiple additional charges, including illegal possession of ammunition, a stolen firearm, suppressor, electronic incapitation device, and drugs will dismissed from the 2023 case at sentencing.

Book’s plea agreement specifies that he will serve a minimum sentence of 60 months in prison for each case — but the sentences will be served concurrently.

Book’s sentencing had not been scheduled by noon Friday.
