delivered the opinion of the court:
The defendant, James R. Bachman, entered pleas of guilty to two counts of deviate sexual assault (Ill. Rev. Stat. 1979, ch. 38, par. 11—3(a)), two counts of aggravated kidnaping (Ill. Rev. Stat. 1979, ch. 38, par. 10—2(a)(5)), and one count of indecent liberties with a child (Ill. Rev. Stat. 1979, ch. 38, par. 11—4(a)(3)). The remaining counts of the 59-count indictment were dismissed pursuant to plea negotiations, which did not, however, encompass sentencing. Defendant was sentenced to terms of 24 years on the deviate sexual assault and aggravated kidnaping convictions and 10 years on the conviction for indecent liberties with a child, all to be served concurrently.
Defendant subsequently moved to withdraw his pleas of guilty. Alternatively, he sought to vacate the sentences imposed, to receive a new sentencing hearing, or to reduce the sentences. At a hearing on the defendant’s post-trial motion, the trial court denied the motion, except that it reduced the sentences for aggravated kidnaping to 15 years. Defendant appeals.
I
We first consider defendant’s contention that he should have been permitted to withdraw his pleas of guilty because they were not understandingly entered, in violation of Supreme Court Rule 402 (87 Ill. 2d R. 402). He claims that he was under the mistaken impression, along with the trial judge, defense counsel and the State’s Attorney, that the aggravated kidnaping charges were Class X felonies when, in fact, none of the indictments charged kidnaping for ransom, and thus the kidnaping charges were Class 1 felonies. (See Ill. Rev. Stat. 1979, ch. 38, pars. 10—2(b)(1), (b)(2).) Trial counsel, in an affidavit, stated that he had advised the defendant that because aggravated kidnaping was a Class X felony, it made little difference relative to sentencing if he pleaded guilty to the deviate sexual assault charges, which were Class X felonies (Ill. Rev. Stat. 1979, ch. 38, par. 11—3(b)).
Whether to permit a plea of guilty to be withdrawn is within the sound discretion of the trial court, not to be disturbed “unless it appears that the guilty plea was entered through a misapprehension of the facts or of law, that defendant has a defense worthy of consideration, or where there is doubt of guilt of the accused and the ends of justice would better be served by submitting the case to a trial.” (People v. Spicer (1970),
Here it is clear that all parties, including the judge, were under the mistaken impression that 30 charges of aggravated kidnaping which were being dismissed were Class X felonies, punishable by imprisonment for not less than six nor more than 30 years when, in fact, they were Class 1 felonies punishable by imprisonment for not less than four nor more than 15 years. (Ill. Rev. Stat. 1979, ch. 38, pars. 1005—8—1(a)(3), (a)(4).) However, not every misstatement of law will entitle a defendant to a withdrawal of his plea unless substantial prejudice is demonstrated. (See People v. Goodwin (1971),
People v. Woodruff (1977),
Other cases cited by the defendant are inapposite as they focus upon rendering a guilty plea void due to the State’s unfulfilled promises. Here there were no unfulfilled promises, since the agreement was to dismiss all the remaining counts without reference to their exact classification.
II
Defendant next asserts that, where multiple convictions are tainted by improper sentencing, the cause must be remanded for re-sentencing. People v. Jones (1980),
III
The defendant also argues that the court’s conduct at the sentencing hearing prejudiced him.
A
At the sentencing hearing certain poems written by the defendant which depicted fictionalized acts of violence, including murder and rape, were introduced into evidence. In support of his position that a new sentencing hearing should be granted due to the admission of the poems, defendant primarily relies on People v. Devin (1982),
There is also substantial difference in introducing testimony which may possibly mislead a jury in imposing the death sentence and in offering information to a sentencing judge who may search anywhere within reasonable bounds for accurate information concerning a defendant’s life and characteristics. See, e.g., People v. Meeks (1980),
Moreover, it is apparent from the record that the trial judge did not consider the poems in imposing sentence. At the hearing on the motion to reduce the sentences the judge expressly stated that the poems were “not relevant according to the court” and were “not considered by the court,” and no claim of a violation of defendant’s rights arises. See People v. Poll (1980),
B
Defendant also contends that he was prejudiced by the State’s improper argument at the sentencing hearing: (1) that defendant is likely to commit the crimes again due to his lack of education and employable skills, (2) that defendant acts out his fantasies in his poems, and (3) that defendant was guilty of exceptionally brutal or heinous conduct indicative of wanton cruelty. Even if there were error, and we find none, the argument is waived by defense counsel’s failure to object. (See, e.g., People v. Reynolds (1980),
C
Defendant also argues that his privilege against self-incrimination was violated at the sentencing hearing by the introduction of statements he made during his presentencing interviews, since they were given without explicit Miranda warnings. We conclude that Miranda warnings are not required in connection with the submission by a defendant to a routine authorized presentence interview. See Baumann v. United States (9th Cir. 1982),
Defendant’s reliance on Estelle v. Smith (1981),
D
Defendant has also argued that his sentences are excessive. There is no evidence in the record that the trial judge was unmindful of the testimony of witnesses who said that defendant was respectful, friendly and nonviolent, or of the provision of the presentence report describing his superior intellectual ability and his good employment record. It can be presumed that the sentencing judge considered this evidence in determining the appropriate sentences. (See People v. Bergman (1984),
E
Finally, defendant argues that he was denied effective assistance of counsel. He charges that his trial counsel was incompetent because his advice as to whether aggravated kidnaping was a Class X or a Class 1 felony was erroneous, because he failed to inform him that any discussion of his prior drug use during his psychological interview could be used against him in sentencing, and because he failed to object to improper arguments by the State at the sentencing hearing. From our view of the entire record we conclude that there has been no showing of incompetence under the general requirement that the representation must produce substantial prejudice to the defendant without which the results would probably have been different. See People v. Royse (1983),
The judgments of the circuit court of Du Page County are therefore affirmed.
Affirmed.
