Following a jury trial in the circuit court of Cook County, defendant, Michael Bryant, and co-defendant Donald Elam were convicted of murder, attempted murder, armed robbery, home invasion, and residential burglary.*fn1 Bryant was sentenced to 80 years imprisonment for the murder conviction; 30 years imprisonment for the attempted murder, armed robbery, and home invasion convictions; and 15 years imprisonment for the residential burglary conviction. The 15- and 30-year terms were to run concurrently with each other, but consecutive to the 80-year term. On appeal, defendant raises the following issues for review: (1) his fifth amendment right to the assistance of counsel was violated when the trial court admitted into evidence uncounseled, incriminating statements which were elicited after he had invoked his right to counsel; (2) defendant was denied a fair trial when the trial court improperly admitted evidence of other charges against defendant, which were not material to the pending case and which may have led the jury to believe he had a propensity to commit crimes; (3) defendant was denied a fair trial where the trial court summarily rejected the jurys request for a copy of the transcript of the complaining witness testimony, and the court refused the jurys request to define "abet"; and (4) the trial court used the wrong standard to evaluate defendants objection to the States use of its peremptory challenges. Defendant also claims that the extended-term sentencing structure under which the court sentenced him is unconstitutionally vague.
