¶1Rivero appeals from his sentences imposed after a jury convicted him of delivery of cocaine,1 and possession of a controlled substance.2 He received concurrent 15 and 25 year sentences, which departed above the permitted range under the guidelines. The reason given for departure was:
Defendant released from DOC on 10/6/88 after serving 2Vh years for deliv*428ery of cocaine and committed this offense of delivery of cocaine on 10/29/88, less than 30 days after released.
¶2Although this court has held that the commission of one offense shortly after release from prison may be relied upon as establishing (in part) a persistent pattern of criminal activity,3 nevertheless, the trial judge must still find a pattern of criminal conduct exists.4 Here, the trial judge merely finds temporal proximity of the two offenses. That is not enough to constitute a “persistent pattern.” Because we cannot assume that the trial judge found a persistent pattern, we vacate the sentence and remand for the purposes of clarification.
