Background
In January 2023, Madison Police Department Officer Jason Laxer stopped Ahmad Grant—a convicted felon—for a defective paper tag on his red Porsche on I-55. During the stop Laxer smelled marijuana, performed a safety pat-down, and then searched the vehicle. Under the driver’s seat he found a pistol. Before Laxer even showed him the gun, Grant spontaneously told the officer it belonged to his brother and assured Laxer the weapon was “clean”—police slang meaning it was not stolen. Dispatch confirmed the opposite: the firearm had been reported stolen in 2019 by Grant’s mother, Sarah Alexander, who had kept it for work as a security guard and stored it at the residence she shared with Grant. Grant was arrested and later indicted for possession of a firearm by a felon and possession of a stolen firearm.
At trial, Grant called his lifelong friend and next-door neighbor Nique Wilson, who testified that he had borrowed the Porsche the evening before the stop, placed his own gun under the driver’s seat, and forgot it there—without telling Grant. Wilson also claimed the gun had been given to him years earlier by Grant’s mother. The State rebutted with three witnesses: a cellphone-location expert who testified that data extracted from Grant’s phone showed it never left Canton, Mississippi, that night (contradicting Wilson’s claim Grant was in New Orleans); a law enforcement expert who identified Wilson as throwing gang signs in a Facebook photo; and a Mississippi Department of Corrections employee who testified that Grant’s booking records showed he had identified himself as a Four Corner Hustlers affiliate. The gang evidence was offered under Mississippi Rule of Evidence 616 to show Wilson’s bias in taking responsibility for the gun. The court gave limiting instructions restricting use of the gang evidence to the bias inference. The jury convicted Grant on both counts, and he was sentenced to fifteen years.
On appeal, Grant raised four issues: sufficiency of evidence on each count, admission of the gang-affiliation evidence, and qualification of the cellphone-location officer as an expert.
The Court’s Holding
The Mississippi Court of Appeals affirmed all convictions and sentences. On constructive possession, the court applied the rule that an owner and sole occupant of a vehicle is presumed to constructively possess items found in it—a rebuttable presumption. Grant’s own statement before seeing the gun (claiming it belonged to his brother), combined with the fact that the gun was his mother’s stolen weapon taken from the very address where Grant had lived his whole life, provided more than enough circumstantial evidence for the jury to reject Wilson’s exculpatory account. On the stolen-firearm count, the court found that Grant’s knowledge that the weapon was stolen could be inferred from the same facts: it was his mother’s work-assigned firearm, stolen from their shared home over three years earlier, and Grant’s “clean” comment showed he was aware of its status.
On the gang evidence, the court confirmed that MRE 616 permits proof of a witness’s bias or interest in the outcome, and that shared gang membership between a defense witness and the defendant is a recognized form of such bias under Mississippi precedent (Dao v. State; Street v. State). The limiting instructions further neutralized any risk that the jury would use the evidence as propensity proof. On the cellphone-location testimony, the court found no abuse of discretion in qualifying Madison PD Officer Wigley as an expert: he had over ninety hours of specialized training from the Secret Service, Cellebrite, and GrayKey; was certified to operate equipment costing $60,000–$80,000 annually; and had performed more than one thousand extractions over ten years. The court also noted that failure to address every Daubert factor verbatim is not fatal under Mississippi law—the Daubert factors are illustrative, not a mandatory checklist.
Key Takeaways
- Under Mississippi law, an owner and sole occupant of a vehicle is presumed to constructively possess items found in it; a defendant’s own pre-arrest statements that contradict the defense witness’s exculpatory account can be decisive circumstantial evidence supporting that presumption.
- Mississippi Rule of Evidence 616 permits the State to introduce evidence of shared gang membership to show a defense witness’s bias—provided the court gives a contemporaneous limiting instruction restricting use of the evidence to the bias inference.
- Expert testimony on cellphone-location data (CSLI / device extraction) does not require verbatim compliance with the Daubert factors; extensive practical training, professional certification, and a high volume of prior extractions can satisfy MRE 702’s reliability requirement.
- An appellate challenge to the State’s failure to pre-designate a rebuttal expert is waived if defense counsel did not request a continuance at trial; the procedural bar extends to the Daubert challenge on appeal.
Why It Matters
Grant v. State is a useful primer for Mississippi criminal practitioners on two evidentiary battlegrounds that increasingly arise in felony firearm cases. Gang-membership evidence is routinely offered to attack the credibility of alibi or exculpatory defense witnesses, and this opinion confirms that the approach is sound under MRE 616 as long as the trial court tethers the evidence to the bias inference with a limiting instruction. Prosecutors and defense counsel should both anticipate the issue and litigate the limiting instruction carefully—if the instruction is wrong, it may be the only avenue for reversal once the evidence is in.
On cellphone-location evidence, the opinion reflects the growing comfort of Mississippi courts with digital forensics experts and reinforces that Daubert is not a formal checklist. For defense counsel, the takeaway is practical: if the State announces a forensics expert mid-trial and no Rule 702 hearing has been held, request a continuance immediately. Failing to do so forfeits both the discovery-violation argument and the full Daubert challenge on appeal.
