Carter and co-defendant Jerry Yancey face federal conspiracy charges for allegedly distributing methamphetamine between January 2024 and May 30, 2024, when Arkansas State Trooper Mitchell Butler pulled over their Kia Forte and discovered over 500 grams of methamphetamine hidden in a black magnetic box under the hood. During a post-arrest interview, Carter told Drug Enforcement Administration agents she was taking Yancey to meet her source of supply, known as 'Chuck,' in Indianola, Mississippi, and that Yancey had paid $2,300 for the drugs.

Prosecutors argue Carter's admission that she had previously taken other individuals from central Arkansas to buy narcotics from the same supplier should be admitted either as intrinsic evidence or under Federal Rule of Evidence 404(b) to prove her knowledge, intent, and motive. As Assistant U.S. Attorney Stacy Williams wrote in the motion, 'A jury is entitled to know the circumstances and background of a criminal charge. It cannot be expected to make its decision in a void—without knowing of the time, place, and circumstances of the acts which form the basis of the charge.'

The government's motion emphasizes that Carter's earlier drug trafficking activities follow an identical pattern to the charged conspiracy, writing that 'the circumstances and the nature of her relationship with 'Chuck' strongly indicate that the prior events did not occur too remotely in time.' Carter told agents that Chuck instructed her to retrieve methamphetamine from a mailbox at his residence and leave payment in the same location, the same method allegedly used in the charged conspiracy.

The case began when Trooper Butler conducted the May 30, 2024 traffic stop that led to the discovery of the methamphetamine cache. Both Carter and Yancey had parole waivers on file, and after a K-9 search revealed the drugs, Carter provided a Mirandized interview to DEA Special Agent Kolton Lane and Agent Jim Wilson. A federal grand jury returned a superseding indictment against both defendants on April 1, 2025.

Carter has pleaded not guilty to the charges, which prosecutors argue places her state of mind at issue and makes the prior bad acts evidence admissible under Eighth Circuit precedent. The government contends that 'evidence of similar prior drug activity is admissible in drug prosecution cases because a defendant's complicity in other similar transactions serves to establish intent or motive to commit the crime,' citing multiple circuit court decisions supporting admission of such evidence.

The Eighth Circuit has established that Rule 404(b) evidence must meet four criteria: relevance to a material issue, similarity and reasonable temporal proximity to the charged crime, sufficient supporting evidence, and probative value that outweighs prejudicial effect. Prosecutors argue Carter's own admission to federal agents satisfies the evidentiary standard, noting that 'the standard for admission of the 404(b) testimony was whether the bad acts are proven by a preponderance of the evidence.'

The government acknowledges that Carter did not provide specific dates for when she took other conspirators to Mississippi, raising the possibility that some activities occurred before the January 2024 start of the charged conspiracy period. However, prosecutors maintain that any potential unfair prejudice can be addressed through limiting jury instructions, a remedy the Eighth Circuit has repeatedly endorsed in similar drug trafficking cases.
