People v. Jackson

Summary

The Illinois Supreme Court affirmed the defendant's first-degree murder conviction and sentence, holding that the evidence was sufficient for a rational jury to find guilt beyond a reasonable doubt. The court also held that two prosecutorial mischaracterizations during closing argument were isolated and nonprejudicial, and that counsel's failure to object did not establish ineffective assistance. Although the trial court improperly allowed adversarial prosecutorial participation during the preliminary ineffective-assistance inquiry, the error was harmless beyond a reasonable doubt because the record showed that the defendant's claims concerned trial strategy and would have been denied regardless.
