Waiver of Rule 14 Severance Without Renewal at Close of Evidence; Proper Joinder of Similar Bank Robberies and Identity Proof by Modus Operandi

1. Introduction

In United States v. Christopher Porter (7th Cir. Apr. 15, 2026) (nonprecedential), the Seventh Circuit affirmed a jury’s convictions of Christopher Porter for three bank robberies under 18 U.S.C. § 2113(a) and one count of brandishing a firearm during a crime of violence under 18 U.S.C. § 924(c)(1)(A)(ii).

The case arose from three similar Chicago-area robberies over roughly four months: a Citibank robbery (Nov. 13, 2020), a Chase robbery (Dec. 22, 2020), and a Fifth Third robbery (Feb. 4, 2021). Porter was arrested shortly after the third robbery following GPS tracking of a silver Ford Explorer linked to the crimes; cash, clothing consistent with the robber, and a Fifth Third coin tray were found on his person and/or in the vehicle.

On appeal, Porter raised two main issues: (1) sufficiency of the evidence identifying him as the robber in the first two incidents (Nov. and Dec.), and (2) alleged error in trying all three robberies together (joinder/severance). The Seventh Circuit rejected both challenges and also addressed an appellate-procedure problem: defense counsel’s failure to include a key severance order in the appendix, despite certifying compliance with circuit rules.

2. Summary of the Opinion

  • Sufficiency (Rule 29): The court held that a rational jury could find Porter guilty of the November and December robberies based on vehicle-link evidence, physical-description evidence, and identity proof strengthened by similarities across the three robberies (modus operandi), alongside strong proof on the February robbery.
  • Joinder (Rule 8(a)): Joinder was proper because the three robbery counts were the same statutory offense and the § 924(c) count arose from the December robbery.
  • Severance (Rule 14(a)): Porter waived severance arguments by not renewing his severance motion at the close of evidence; the court found no basis to excuse waiver as “futile.”
  • Appendix / certification: The court admonished counsel for a false certification under Circuit Rule 30(d), but concluded it did not prejudice Porter because the panel located and reviewed the missing severance order.

3. Analysis

3.1. Precedents Cited

The court’s analysis is built around three doctrinal clusters—(a) the sufficiency standard, (b) identity-by-modus-operandi evidence, and (c) joinder/severance (including waiver).

A. Sufficiency of the evidence / Rule 29

  • United States v. Jackson, 5 F.4th 676 (7th Cir. 2021) (quoting Musacchio v. United States, 577 U.S. 237 (2016)): The panel restated the governing sufficiency standard—view evidence in the light most favorable to the government and ask whether “any rational trier of fact could have found” guilt beyond a reasonable doubt.
  • United States v. Doody, 600 F.3d 752 (7th Cir. 2010) and United States v. Garcia, 580 F.3d 528 (7th Cir. 2009): Invoked to underscore the narrowness of appellate review—reversal only if “no rational trier of fact” could convict, a burden described as “nearly insurmountable.”
  • United States v. Stevenson, 680 F.3d 854 (7th Cir. 2012): Used to frame the endpoint inquiry—whether the record is “devoid of evidence” supporting identification; the panel held it plainly was not.
  • United States v. Jackson, 688 F.2d 1121 (7th Cir. 1982): Cited for the unremarkable but important proposition that jurors may compare courtroom appearance with video and witness descriptions.

B. Identity through a “signature” method (modus operandi)

  • United States v. Edwards, 26 F.4th 449 (7th Cir. 2022): The court relied on Edwards for the Rule 404(b)(2) principle that other acts may be used to prove identity if they establish a “unique pattern or signature.” Porter’s three robberies shared multiple features (masked armed robber, teller demand, bag for cash, silver Ford SUV, compressed time frame), allowing the jury to infer a single perpetrator and thus to use strong evidence from one event to reinforce identity in the others.

C. Joinder, severance, and waiver

  • United States v. Coley, 137 F.4th 874 (7th Cir. 2025): Provided the analytic structure: (1) whether joinder was proper under Rule 8 as a legal matter, and (2) whether severance was warranted under Rule 14 to avoid prejudice.
  • United States v. Baldwin, 149 F.4th 959 (7th Cir. 2025): Cited both for Rule 8(a) joinder standards and for the waiver rule—failure to renew a severance motion at the close of evidence waives the argument. Baldwin also supplies the narrow “futility” exception, which the panel found inapplicable here.
  • United States v. Jamal, 87 F.3d 913 (7th Cir. 1996): Used to dispatch Porter’s Rule 8 challenge: when “the charges are the same,” that is sufficient to join them. The panel echoed Jamal’s blunt phrasing that the argument “comes to a screeching halt.”

3.2. Legal Reasoning

A. Why the evidence was sufficient on the November and December robberies

The court emphasized that Porter’s sufficiency challenge was fundamentally an attack on identification. The panel highlighted three reinforcing evidentiary strands:

  1. Getaway vehicle linkage: For the November robbery, video showed a silver SUV with a distinctive decal; the government matched it to Porter’s Ford Explorer through vehicle-location reports and BMV records. For the December robbery, the escape route and license-plate-reader evidence placed Porter’s Explorer on the Kennedy Expressway consistent with the robber’s travel.
  2. Physical-description comparison: Video from November and December, plus employee testimony in December (robber described as a Black man over six feet tall), permitted jurors to compare those characteristics to Porter in court.
  3. Cross-count identity reinforcement (modus operandi): The panel reasoned that the similarities across the three robberies, combined with the especially strong proof tied to the February robbery (GPS tracking, cash on Porter, matching clothing, coin tray), allowed the jury to infer that the same person committed all three—supporting identification on the earlier counts.

Critically, the court did not require any single “smoking gun” for each robbery in isolation; it accepted cumulative proof and permissible inference as adequate for a rational jury.

B. Why joinder was proper, and why severance failed

Under Rule 8(a), joinder is permissible if offenses are of the “same or similar character” or based on the same act/transaction. The panel treated joinder here as straightforward: all three robbery counts were the same statutory crime, and the § 924(c) count arose from the December robbery.

The more substantial dispute—severance under Rule 14(a) due to prejudicial “spillover”—never received merits review because the panel found waiver: Porter did not renew his severance motion at the close of evidence, as required by Seventh Circuit practice (as stated in United States v. Baldwin). The court acknowledged a “futility” escape hatch but found nothing in the district court’s pretrial ruling suggesting that renewal would have been pointless.

C. Appellate-rule enforcement and attorney candor

The panel’s final section underscores that appellate litigation is constrained by procedural rules as well as merits. Citing Circuit Rule 30(b)(1) and 30(d), the court admonished defense counsel for omitting the severance order from the appendix while certifying compliance. The court refrained from a show-cause order but put counsel on notice and reassured Porter that the omission caused no prejudice because the judges obtained and reviewed the missing document.

3.3. Impact

Although designated nonprecedential, the disposition provides practical guidance likely to influence litigants and trial courts in at least four ways:

  • Rule 29 identification challenges remain difficult: The opinion illustrates how vehicle-location evidence, video, and circumstantial links—when viewed cumulatively—will typically suffice under the deferential “rational juror” standard.
  • Similarity across crimes can matter twice: Similarities among charged robberies can support both (a) joinder and (b) identity proof (including via the logic of Rule 404(b)(2)/modus operandi), increasing the prosecution’s ability to present a cohesive narrative across incidents.
  • Severance requires procedural persistence: The waiver holding reinforces that defendants must renew severance at the close of evidence to preserve Rule 14 arguments—even if the court denied severance pretrial.
  • Appellate compliance is not optional: The admonition signals that the Seventh Circuit monitors appendix completeness and attorney certifications, and that omissions can prompt sanctions—even if the court can independently locate missing materials.

4. Complex Concepts Simplified

  • Rule 29 (Judgment of acquittal): After the government’s evidence (or after all evidence), a defendant can ask the judge to throw out a charge because no reasonable jury could convict on the evidence presented.
  • Sufficiency review (“any rational trier of fact”): On appeal, judges do not re-weigh credibility. They assume the jury believed the government’s evidence and drew reasonable inferences from it.
  • Rule 8(a) (Joinder): Allows the government to charge multiple offenses together when they are similar or connected; it is about administrative and evidentiary efficiency, not fairness.
  • Rule 14(a) (Severance for prejudice): Even if joinder is allowed, a judge can split charges into separate trials if a combined trial would unfairly prejudice one side (commonly “spillover,” where evidence on one charge improperly affects deliberations on another).
  • Rule 404(b)(2) and “modus operandi”: Evidence of other acts is usually not admissible to show a person’s bad character, but it can be used to prove identity when the crimes share a distinctive “signature” method suggesting the same perpetrator.
  • Waiver by failure to renew: Some trial motions must be renewed after the evidence is presented; if not, appellate courts often treat the issue as forfeited/waived.

5. Conclusion

The Seventh Circuit affirmed Porter’s convictions by applying familiar but powerful doctrines: a highly deferential sufficiency standard, permissive joinder for similar offenses, and strict preservation rules for severance requests. The court’s key practical lessons are that cumulative circumstantial identification evidence can readily sustain robbery convictions, similarities among crimes may legitimately reinforce identity, and defendants must renew severance motions at the close of evidence to preserve Rule 14 claims. Finally, the opinion serves as a cautionary note on appellate professionalism: omissions in the appendix coupled with false compliance certifications can draw pointed judicial reprimand.
