32 F.4th 377
4th Cir.2022Background
- Charles Anthony Walker Jr. recruited accomplices (Brown, Maynard, Chambers) and planned armed jewelry-store robberies in July and October 2018; he provided vehicles, clothes, guns, and coordinated movements.
- July 28, 2018 (Elizabeth City): two co-defendants entered Kay Jewelers armed while Walker remained in the store and then left; victims testified about being handcuffed and robbed of high-value merchandise.
- October 11, 2018 (Garner): Walker drove a vehicle, supplied vests, pillowcases, and firearms; two co-defendants robbed a mall Kay Jewelers and fled; Walker later helped fence the loot.
- While jailed and under investigation Walker authored at least one intercepted letter urging others to call a cooperating witness (Sparks) an informant; Sparks later received screenshots of similar letters and testified he felt threatened.
- Walker was indicted and convicted of conspiracy to commit Hobbs Act robbery, two Hobbs Act robberies, brandishing a firearm, and witness tampering; he appealed, raising evidentiary objections and a sufficiency challenge to the witness‑tampering conviction.
Issues
| Issue | Plaintiff's Argument (Government) | Defendant's Argument (Walker) | Held |
|---|---|---|---|
| Admission of victim testimony about long‑term psychological/ life effects | Testimony shows victims feared injury and helps prove robbery impact | Irrelevant to elements and unfairly prejudicial (victim‑impact style) | Admission was erroneous but harmless; evidence against Walker was overwhelming, so conviction stands |
| Victim testimony that Walker was the “decoy”/was “acting afraid” (lay opinion) | Victims’ perceptions were based on contemporaneous observations and helped explain events | Improper lay opinion given chaotic circumstances | Properly admitted as permissible lay opinion grounded in victims’ perceptions |
| Case agent Robertson’s interpretation of recorded jail calls (e.g., “mission,” basketball code) | Agent listened to calls and his interpretation aids jury | Improper post‑hoc lay opinion; agent did not participate or contemporaneously hear meanings | Admission was error: agent’s speculative, investigatory interpretations should be excluded as lay testimony or offered only as qualified expert testimony when appropriate |
| Admission/authentication of screenshots sent to Sparks and testimony that Walker was dangerous | Screenshots and letters are circumstantially linked to Walker and probative of intimidation; Sparks’s view of danger explains impact | Screenshots not tied to Walker; intercepted letter was never delivered, so no tampering | Screenshots were adequately authenticated and Sparks’s testimony probative of witness‑tampering intent; admission proper and not unduly prejudicial |
| Sufficiency of evidence on witness tampering (18 U.S.C. §1512(b)) | Intercepted letter + screenshots + Sparks’s testimony + other threats show intent to intimidate/ prevent testimony; attempted tampering sufficient | Letter intercepted and undelivered means no tampering; insufficient proof Walker tried to influence Sparks | Evidence was sufficient for a reasonable juror to convict of attempted witness tampering; motions for acquittal properly denied |
