there were none, rejecting arguments based on appellant’s unfavorable background and the failure of state rehabilitation authorities to intervene.
Even though the trial judge did not instruct the jury on the aggravating circumstance of whether appellant had previously been convicted of a felony involving the threat or use of violence to another person, he himself found it to be an aggravating circumstance. He did so on the basis of the contemporaneous convictions for kidnapping and attempted first-degree murder. This was proper. See Ruffin v. State, 397 So.2d 277 (Fla.), cert. denied, 454 U.S. 882, 102 S.Ct. 368, 70 L.Ed.2d 194 (1981); Lucas v. State, 376 So.2d 1149 (Fla.1979).
The judge also properly found that appellant knowingly created a great risk of death to many persons. See Lucas v. State; Raulerson v. State, 358 So.2d 826 (Fla.), cert. denied, 439 U.S. 959, 99 S.Ct. 364, 58 L.Ed.2d 352 (1978). The murder occurred during a raging gun battle with the police with three hostages present.
There is no question that the murder was committed while appellant was engaged in the commission of a felony, in this case kidnapping, and that it was committed for the purpose of avoiding or preventing a lawful arrest. The finding that the murder was committed for pecuniary gain is supported by the trial court’s finding that appellant had planned a bank robbery for several months and had proceeded as far as the hostage stage before he was interrupted. The fact that the robbery was never completed is irrelevant so long as there was an attempt. See Mikenas v. State, 367 So.2d 606 (Fla.1978).
Appellant next challenges the judge’s refusal to find any of the statutory mitigating factors present. He claims that he had no significant history of prior criminal activity as an adult. However, he had attempted an armed robbery and a bombing of a school when he was minor. Since the purpose of this mitigating factor is to help ascertain a defendant’s character, we do not believe that a trial judge should be limited to looking at a defendant’s adult criminal activity. A defendant’s juvenile record can be just as relevant in determining the defendant’s character. Because appellant’s prior criminal activity as a minor was significant, the judge properly found this not to be a mitigating factor.
Appellant also argues that his emotional condition should have been considered as a mitigating circumstance under subsections 921.141(6)(b), (e), and (f), Florida Statutes (1979). There was lay testimony that appellant had mental problems. This was corroborated by a clinical psychologist’s testimony that appellant was someone of dull-normal intelligence with grandiose feelings and by a psychiatrist’s testimony that appellant had a schizoid personality. All of this testimony was considered and rejected by both the jury and the judge. That decision was theirs and not ours to make. Since there was nothing in the record to indicate that their conclusions or the methods followed in reaching them were improper, we accept their conclusions.
Smith v. State, 407 So.2d 894 (Fla.1981),
cert. denied, 456 U.S. 984,102 S.Ct. 2260, 72 L.Ed.2d 864 (1982);
Lucas v. State; Hargrave v. State, 366 So.2d 1 (Fla.1978),
cert. denied, 444 U.S. 919, 100 S.Ct. 239, 62 L.Ed.2d 176 (1979).
Appellant argues that the court erred in not finding his age, twenty years, to be a mitigating circumstance. “There is no per se rule which pinpoints a particular age as an automatic factor in mitigation.” Peek v. State, 395 So.2d 492, 498 (Fla.), cert. denied, 451 U.S. 964, 101 S.Ct. 2036, 68 L.Ed.2d 342 (1981). In this case the record supports the judge’s decision not to consider appellant’s age as a mitigating circumstance.
Finally appellant argues that his right against double jeopardy was violated by the judge’s imposing separate sentences for the three counts of kidnapping. He relies on State v. Pinder, 375 So.2d 836 (Fla.1979), where this Court held that in a felony-murder prosecution, the double jeopardy clause bars separate conviction and
