Can surveillance testimony alone support drug distribution convictions? State v. Blais Explained

In State v. Blais, the Utah Court of Appeals addressed whether officer surveillance testimony combined with forensic evidence provides sufficient proof for drug distribution and possession convictions, even when the defendant challenges the chain of custody.

Background and Facts

Officer surveillance from four stories above observed Blais, his daughter, and another man conducting drug transactions on the street. Using a spotting scope, the officer witnessed approximately a dozen transactions involving “twists” (small plastic packages containing drugs). The officer observed buyers giving money to the daughter, who directed them to Blais, who then provided substances from his backpack or mouth. After witnessing Blais hand a buyer a black twist, officers arrested the buyer and found the black twist containing heroin. Officers then arrested Blais and searched his black and gray backpack, finding two white twists that tested positive for cocaine.

Key Legal Issues

Blais challenged the sufficiency of evidence for both distribution and possession charges, arguing insufficient proof that the substances found and tested were the same ones involved in the transactions. He also contested the district court’s denial of his motion to reduce his enhanced felony convictions and claimed his one-year sentence for a class C misdemeanor was illegal.

Court’s Analysis and Holding

The court applied plain error review to the unpreserved sufficiency claims, requiring demonstration that any insufficiency was “obvious and fundamental.” The court found sufficient evidence where the surveillance officer maintained continuous observation, the buyer was immediately arrested with the black twist, proper evidence booking procedures were followed, and forensic testing confirmed the substances. The court noted that reasonable inferences connecting the observed transactions to the tested substances were appropriate for jury consideration. However, the court reversed the misdemeanor sentence as exceeding the 90-day statutory maximum for class C misdemeanors.

Practice Implications

This decision reinforces that chain of custody challenges must be preserved at trial to receive meaningful appellate review. The court’s analysis demonstrates that continuous surveillance testimony, combined with proper evidence handling and forensic confirmation, typically provides sufficient evidence for drug convictions even without DNA or fingerprint evidence.
