People v. Harris

Summary

The court held that the evidence was sufficient to prove Harris guilty of murder beyond a reasonable doubt. It reversed the appellate court's determination that his mandatory 76-year aggregate sentence violated the Illinois proportionate penalties clause because Harris had not developed an evidentiary record supporting his as-applied challenge. The court also held that the Eighth Amendment does not extend juvenile sentencing protections to offenders who were 18 or older at the time of the offense.
