The question presented is whether a sentence for the crime of escape may be made consecutive not only to the sentence(s) being served when the escape occurred but also to another sentence imposed for a separate crime committed by the escapee while he was at large. Based upon the language of Idaho’s escape statute, we hold that the escape sentence must begin upon discharge from the sentence(s) being served when the escape occurred.
The question is framed by the following facts. Michael McKaughen escaped from custody in Idaho while serving a thirteen-year prison sentence for robbery. 1 Making his way to Oregon, he participated in another robbery. He was apprehended, convicted and sentenced to twenty years in the Oregon State Penitentiary. He later pled guilty in Idaho to a charge of escape. The Idaho district court sentenced McKaughen to an indeterminate term of three years for escape, ordering that the sentence run consecutively to both the Idaho and Oregon robbery sentences. McKaughen appealed. We vacate the escape sentence and remand the case.
McKaughen does not dispute the Idaho judge’s duty to make the escape sentence consecutive to the Idaho robbery sentence. That duty is mandated by the escape statute, I.C. § 18-2505, which we will examine more fully later in this opinion. Rather, McKaughen’s narrow challenge to the escape sentence is directed at making it consecutive to the Oregon robbery sentence also.
We begin our analysis by noting that an Idaho court has inherent authority to impose consecutive sentences.
State v. Lawrence,
But that is not the end of our inquiry. The next question is whether such general authority is limited in this case by I.C. § 18-2505. Unlike I.C. § 18-308, I.C. § 18-2505 is not discretionary; it is mandatory. It not only authorizes con *473 secutive sentencing but specifies how the sentences shall be structured in escape cases. It provides as follows:
Every prisoner charged with or convicted of a felony who is confined in any jail or prison including the state penitentiary, or who while outside the walls of such jail or prison in the proper custody of any officer ... escapes ... shall be guilty of a felony, and upon conviction thereof, any such second term of imprisonment shall commence at the time he would otherwise have been discharged. [Emphasis added.]
Although the statute refers to a “second term of imprisonment,” this phrase, when viewed against the legislative history, simply means that the escape sentence and the sentence(s) being served when the escape occurred must be consecutive.
State v. Mendenhall,
In our view, the statute has a plain meaning. It does not allow for a time interval between discharge of the sentence^) being served when the escape occurred and commencement of the escape sentence. Accordingly, in the present case, there could be no interval between the Idaho robbery sentence and the escape sentence. To the extent that such an interval would be created by making the escape sentence consecutive to both the Idaho robbery sentence and the longer Oregon robbery sentence, the escape sentence would contravene I.C. § 18-2505. 2
It might be suggested that the statute has no clear meaning because an ambiguity lurks in the word “discharged.” The word arguably could refer to discharge only of the sentence(s) the prisoner was serving when he escaped or it could refer more broadly to discharge of all sentences, wherever imposed, that were outstanding when the escape sentence was pronounced. Such an ambiguity, if it exists, has not been addressed by a reported decision construing the statute.

In any event, an ambiguity would not change the result here. Criminal statutes are strictly construed in their substantive elements and in their sanctions.
State v. Thompson,
We conclude that the district court properly made the escape sentence consecutive to the Idaho robbery sentence but erred by making it also consecutive to the Oregon robbery sentence. Therefore, the escape sentence is vacated and the case is remanded for entry of a corrected sentence in accordance with this opinion.
Notes
. The robbery sentence included a three-year enhancement for displaying a firearm during the offense. I.C. § 19-2520.
. For the purpose of this opinion we assume, without deciding, that the Idaho robbery sentence could be the first of the two robbery sentences discharged. The actual relationships between the two sentences, and the discharge practices of Idaho and Oregon correctional authorities, are not elaborated in the record. Consequently, we do not address them here.
