1. In cities and counties having a population of three hundred thousand inhabitants and over, each deputy sheriff, not more than two, shall be allowed for each day during the term of court six dollars, to be paid by the city or county of three hundred thousand inhabitants or over.

2. For the services of taking convicted offenders to the reception and diagnostic center designated by the director of the department of corrections, the sheriff, county marshal or other officers shall receive the sum of eight dollars per day for the time actually and necessarily employed in traveling to and from the reception and diagnostic center, and each guard shall receive the sum of six dollars per day for the same, and the sheriff, county marshal or other officer and guard shall receive the mileage rate prescribed by this section for the distance necessarily traveled in going to and returning from the reception and diagnostic center, the time and distance to be estimated by the most usually traveled route from the place of departure to the reception and diagnostic center; the mileage rate prescribed by this section for each mile traveled shall be allowed to the sheriff to cover all expenses on each convicted offender while being taken to the reception and diagnostic center; and all persons convicted and sentenced to imprisonment in the department of corrections at any term or sitting of the court, shall be taken to the reception and diagnostic center at the same time, unless prevented by sickness or unavoidable accident. In cities having a population of two hundred thousand inhabitants or more, convicted offenders shall be taken to the reception and diagnostic center as often as the sheriff deems necessary. When three or more convicted offenders are being taken to the reception and diagnostic center at one time, a guard may be employed, but no guard shall be employed for a less number of convicted offenders except upon the order, entered of record, of the judge of the court in which the conviction was had, and any additional guards employed by order of the judge shall, in no event, exceed one for every three convicted offenders; and before any claim for taking convicted offenders to the reception and diagnostic center is allowed, the sheriff, or other officer conveying such convicted offender, shall file with the state director of the department of corrections an itemized statement of such sheriff’s account, in which the sheriff shall give the name of each convicted offender conveyed and the name of each guard actually employed, with the number of miles necessarily traveled and the number of days required, which in no case shall exceed three days, and which account shall be signed and sworn to by such officer and accompanied by a certificate from the chief administrative officer or such officer’s designee of the reception and diagnostic center, that such convicted offenders have been delivered at the reception and diagnostic center and were accompanied by each of the officers and guards named in the account.

3. The sheriff or other officer who shall take a person, charged with a criminal offense, from the county in which the offender is apprehended to that in which the offense was committed, or who may remove a prisoner from one county to another for any cause authorized by law, or who shall have in custody or under such sheriff’s or officer’s charge any person undergoing an examination preparatory to such person’s commitment more than one day for transporting, safekeeping and maintaining any such person, shall be allowed by the court having cognizance of the offense, three dollars and fifty cents per day for every day such sheriff or officer may have such person under such sheriff’s or officer’s charge, when the number of days shall exceed one, and the mileage rate prescribed by this section for every mile necessarily traveled in going to and returning from one county to another, and the guard employed, who shall in no event exceed the number allowed the sheriff, marshal or other officer in transporting convicted offenders to the reception and diagnostic center, shall be allowed the same compensation as the officer. Three dollars and fifty cents per day, mileage same as officer, shall be allowed for board and all other expenses of each prisoner. No compensation shall be allowed under this section for taking the prisoner or prisoners from one place to another in the same county, excepting in counties which have two or more courts with general criminal jurisdiction. In such counties the sheriff shall have the same fees for conveying prisoners from the jail to place of trial as are allowed for conveying prisoners in like cases from one county to another, and the expenses incurred in transporting prisoners from one county to another, occasioned by the insufficiency of the county jail or threatened mob violence, shall be paid by the county in which such case may have originated; provided that the court is held at a place more than five miles from the jail; and no court shall allow the expense of a guard, although it may have actually been incurred, unless from the evidence of disinterested persons it shall be satisfied that a guard was necessary; provided, that when the place of conviction is remote from a railroad, upon which a convicted offender may be transported to the reception and diagnostic center, the court before which such convicted offender is sentenced may, for good cause shown, allow one guard for every two convicted offenders, such guard to receive three dollars a day and the mileage rate prescribed by this section for every mile necessarily traveled in going to and returning from the nearest depot on said railroad to the place where such convicted offender was sentenced.

4. Mileage shall be reimbursed to sheriffs, county marshals and guards for all services rendered pursuant to this section at the rate prescribed by the Internal Revenue Service for allowable expenses for motor vehicle use expressed as an amount per mile.
