Chain-of-Custody Authority Failure Under Documentation Gap

Chain of custody procedures govern physical evidence handling in criminal prosecutions, requiring documentation of every transfer from seizure through trial. South Carolina courts mandate prosecutors establish an unbroken chain showing evidence was not tampered with, contaminated, or substituted. Documentation includes officer signatures on transfer forms, timestamps, storage records, and witness testimony confirming each custody transfer.

On June 22, 2013, Timothy Pulley was arrested during a traffic stop in Laurens, South Carolina. Officers recovered three plastic bags containing 16.5 grams of cocaine base from his vehicle. The evidence was seized and transferred through standard custody procedures to the South Carolina Law Enforcement Division for analysis. Each transfer required documentation with signatures, dates, and location information.

The chain of custody documentation showed four recorded transfers: Officer Craven's initial seizure, delivery to the evidence custodian, transfer to SLED for analysis, and return for trial. Each appeared on signed custody forms with timestamps. However, defense counsel identified a critical gap. Dashcam video showed Officer Craven placing the three bags on Officer Brewer's patrol vehicle hood before departing in his own vehicle. The video clearly captured Craven leaving while the evidence remained on Brewer's vehicle.

During testimony, Craven stated he placed the cocaine on Brewer's vehicle hood and later placed it in the evidence locker. When questioned about the transfer between these points, Craven could not provide details. Officer Brewer initially testified he did not transport the evidence. This created a documented gap: Craven departed while evidence was on Brewer's vehicle, but Brewer said he did not take possession.

The prosecution produced no documentary or testimonial evidence establishing custody during the critical transfer period between Craven's departure and the evidence's appearance in the locker. Brewer's initial testimony created a documented gap: Craven left the scene with cocaine on Brewer's vehicle, but Brewer stated he did not take possession. The evidence custodian confirmed he did not receive it from Craven, contradicting the custody form. These testimonial failures, combined with the absence of signed transfer documentation, meant no procedural record existed to verify the evidence's custody during the 30-minute gap.

The trial court ruled that a "logical assumption" could bridge the gap—reasoning that Brewer must have taken the cocaine because he would not have driven away with evidence on his hood. The court determined that while documentation was imperfect, logic filled the gap sufficiently to admit the evidence. This ruling substituted inference for documentation, allowing the trial to proceed despite the custody gap. Following this ruling, the prosecution recalled Brewer to testify again.

Upon recall, Brewer testified he now "remembered" transporting the cocaine after reviewing the dashcam footage shown during trial. He stated seeing the video refreshed his memory about taking custody from his vehicle's hood. However, several problems undermined this revised testimony. First, the dashcam didn't actually show Brewer taking the evidence—only Craven placing it and departing. Second, Brewer admitted he never signed transfer documentation taking custody from Craven or delivering to the locker. Third, his revised testimony directly contradicted his initial sworn statement. The prosecution offered no explanation for why Brewer's memory initially failed, then suddenly returned after the court's favorable ruling.

The South Carolina Supreme Court reversed the conviction on appeal in a unanimous decision issued June 6, 2018. The Court held the State failed to establish a complete chain of custody, rejecting the trial court's reliance on "logical assumption" to fill the documentary gap. The opinion stated that while perfect chain of custody isn't required, "the analysis must not be left to conjecture."

The Court addressed Brewer's contradictory testimony, noting his initial denial followed by subsequent "recollection" after the court's favorable ruling undermined rather than restored evidentiary authority. The dashcam video Brewer claimed refreshed his memory didn't actually show him taking custody—only Craven placing it and departing. Brewer's failure to sign transfer documentation combined with contradictory statements meant his testimony couldn't cure the documentary deficiency.
