The war on drugs continues along I-70 in Emery County as a recent drug bust led to the seizure of 600 doses of LSD, 100 MDMA pills and over five ounces of illegal drugs. This bust occurred at a traffic checkpoint on I-70, where a deputy from the Emery County Sheriff’s Office apprehended Kelsey James Koster and booked her into jail on charges of possession of a controlled substance with intent to distribute.

The deputy’s suspicion was raised when, while assisting with a traffic stop near exit 131, he noticed a silver van take the exit without a turn signal, roll through a stop sign, and stop on the on-ramp.

Acting quickly, the deputy initiated a traffic stop. Of the van’s two occupants, the arrest report singles out Koster. Gathering information, the deputy began a records request while waiting for K-9 assistance.

Upon arrival, the K-9 indicated the presence of drugs.

The vehicle was searched, which led to the discovery of over 138 grams of suspected illegal substances – including what deputies infer to be psilocybin mushrooms, methamphetamine, ketamine and ecstasy. Additionally, the search yielded 557 LSD acid tabs, THC resin, a THC vape cartridge and several items of marijuana paraphernalia.

Following the search, Koster was arrested and booked into the Emery County Jail. She faces six counts of possession of a controlled substance with intent to distribute – a second-degree felony. Other charges include drug possession, a class-A misdemeanor; paraphernalia possession, a class-B misdemeanor; and failure to signal.
