People v. Behning

Court IL Appellate, 1st District
Filed Friday, June 26, 2026
Citation 2026 IL App (1st) 241671

Key Takeaways

  • 1 Courts afford strong deference to trial counsel's witness examination strategy under Strickland's deficiency prong.
  • 2 Showing others had computer access is insufficient to establish prejudice where exclusive control theory was already litigated.
  • 3 Relevant for post-conviction and criminal defense attorneys litigating ineffective assistance claims involving digital forensic evidence.

Summary

Randall Behning was convicted after a bench trial of multiple sexual offenses against his minor stepdaughter and sentenced to 36 years' imprisonment. After his convictions were affirmed on direct appeal, he filed a post-conviction petition that advanced to the second stage. The Cook County circuit court granted the State's motion to dismiss, finding Behning failed to make a substantial showing of a constitutional violation. Behning appealed, arguing trial counsel was ineffective in three respects: inadequately examining witness Kyle Peters, failing to adequately cross-examine Detective Carla Carter on forensic evidence, and failing to call expert witness Patricia Glees.

The Illinois First District Appellate Court affirmed the dismissal on all three claims, applying the two-prong Strickland test. On the Peters and Glees claims, the court held that counsel's decisions regarding witness examination and witness selection are matters of trial strategy entitled to substantial deference, and Behning's allegations amounted to disagreements with strategic choices rather than constitutional deficiencies. On the Carter and Glees claims, the court further found no prejudice, reasoning that even if the proposed testimony had been elicited, it would have shown only that others may have had access to the computer — a theory trial counsel had already advanced — without establishing that someone else actually created or controlled the relevant files.

This decision reinforces that post-conviction petitioners face a high bar at the second stage when challenging trial strategy, particularly where counsel already presented the underlying theory at trial. Attorneys handling post-conviction matters should carefully distinguish between supplementing a theory already before the factfinder and presenting genuinely new, outcome-altering evidence.

Key Holdings

1. Trial counsel's decisions regarding the scope and manner of witness examination constitute matters of trial strategy entitled to substantial deference, and allegations that counsel should have asked additional questions or pursued a different approach are generally insufficient to overcome the strong presumption of sound strategy under Strickland's deficiency prong.

2. A post-conviction petitioner fails to make a substantial showing of Strickland prejudice where the proposed additional testimony would merely supplement a theory already presented to the factfinder, without creating a reasonable probability of a different result.

3. Evidence that other individuals had access to a computer does not, without more, establish that someone other than the defendant created, possessed, modified, or controlled the relevant files, and is insufficient to demonstrate prejudice where the factfinder already considered and rejected an access-by-others defense.

4. Decisions concerning whether to call a particular witness are matters of trial strategy, and a petitioner challenging the failure to call a witness must show both deficient performance and a reasonable probability that the witness's testimony would have changed the outcome of the trial.
