After the Alabama Supreme Court remanded the denial of defendant's postconviction relief petition for findings on whether defense counsel's firearms expert was qualified, the trial court made such findings. The appellate court held the trial court properly found the witness was qualified because the court (1) thoroughly examined the witness's testimony and, from that testimony, found the witness had the necessary knowledge, skill, and experience to qualify as an expert and (2) applied the proper standard, which was whether the witness had acquired knowledge beyond that of an average layperson.
