Dillbeck was convicted of first-degree murder, armed robbery, and armed burglary. In connection with Dillbeck's sentencing, the trial court considered various statutory and non-statutory mitigating circumstance, including that Dillbeck has FAE and that his capacity to conform his conduct to the requirements of the law was substantially impaired, but also found that there were numerous aggravating circumstances. Following the jury's recommendation, the trial judge sentenced Dillbeck to death. Dillbeck's arguments on appeal included ineffective assistance of counsel, claiming, among other things, that his attorney failed to request a PET scan. (The Court's opinion does not indicate whether the request for a PET scan was related to the fact that Dillbeck has FAE.) The circuit court denied relief, and Dillbeck appealed, seeking a writ of habeas corpus. Dillbeck's petition did not appeal the claim that counsel should have requested a PET scan, so although the court remanded the case to the circuit court to enter further findings with respect to Dillbeck's claims, it held that the circuit court need not address Dillbeck's claim with respect to the failure to request a PET scan.
