The trial court did not abuse its discretion in qualifying a computer forensic analyst as an expert in forensic computer analysis and permitting him to opine on whether recovered images depicted real rather than virtual children. The related discovery objection was waived. The court applied the Illinois common-law qualification standard rather than a Frye general-acceptance analysis to this witness.

The court’s reasoning
Illinois permits expert testimony where the witness's experience and qualifications afford knowledge not common to lay persons that will aid the trier of fact, and expertise may be acquired through practical experience rather than academic credentials. The witness's role as lead computer evidence recovery technician, his peer review of other examiners' forensic evaluations, and his construction of a database of images of known children supplied that foundation. Reliance on discussions with graphics professionals and on database entries supplied by investigators did not make the opinion inadmissible hearsay.
From the opinion
“an individual will be permitted to testify as an expert if his experience and qualifications afford him knowledge which is not common to lay persons and where such testimony will aid the trier of fact in reaching its conclusion.”
Grounds argued
This ruling turned on 2 of the eight arguments that recur across the docket. Each is defined the same way on every entry, so the same ground can be followed across rulings that reached opposite results.
- Qualifications
- Whether this witness — by training, certification, or documented casework — is competent to give this opinion. Courts routinely admit examiners qualified by experience alone, and routinely narrow them when the opinion strays past the experience they described.
- Fit to the issue
- Whether the opinion helps decide a fact actually in issue. Testimony can be entirely reliable and still be excluded because it answers a question the case does not ask.
