People v. Lacy 

Defendant was convicted, after jury trial, of aggravated criminal sexual assault and armed robbery. Defendant failed to make a substantial showing of a constitutional violation as he did not show that counsel was ineffective during counsel's examination of victim at suppression hearing, at trial, or on appeal, and thus court properly dismissed Defendant's postconviction petition at second stage. Manner of cross-examination and decision whether to impeach witness are matters of trial strategy of professional judgment. Even if court erred in admitting evidence of K-9 ("bloodhound") tracking, Defendant was not prejudiced as tracking led to two blocks from where Defendant was later arrested, and both victims gave multiple strong identifications of Defendant. (CAHILL and McBRIDE, concurring.)
