Two individuals from Big Lake are facing felony drug charges after law enforcement executed a search warrant at their residence and allegedly discovered fentanyl and cocaine in locations accessible to a child, according to a criminal complaint filed in Sherburne County District Court.

Maggie Elizabeth Uselton, 31, and Mason William Brown, 28, have both been charged with one felony count of 5th Degree Drug Possession (Schedule 1, 2, 3, 4) and one gross misdemeanor count of Endangering a Child in a Situation Could Cause Harm or Death.

According to the complaint, on or about December 10, 2025, Sherburne County law enforcement officers executed a search warrant at a residence on Henry Road in Big Lake. Officers made contact with Uselton and Brown in their vehicle as they arrived at the garage.

Upon removing the defendants from the vehicle, officers allegedly observed that Brown appeared to be heavily under the influence of a controlled substance. The complaint states there was an “overwhelming chemical odor consistent with fentanyl being consumed in the vehicle.” Officers noted a car seat in the rear of the vehicle and arranged for a relative to take custody of Victim 1, a child who would normally have been returning to the residence.

During a search of the vehicle, officers allegedly discovered a plastic container in the center console next to where Brown was seated. The container held a white powder substance that field-tested positive for cocaine and fentanyl, weighing approximately 1.0 grams.

Officers also located a purse belonging to Uselton in the vehicle. Inside, they allegedly found another plastic container with a substance that field-tested positive for both cocaine and fentanyl, weighing 2.14 grams. A digital scale and Narcan were also reportedly found in the purse.

According to the complaint, Uselton provided a Mirandized statement admitting to using fentanyl the morning the warrant was executed. She allegedly indicated that Brown had been smoking fentanyl in the vehicle that day, and admitted that she and Brown smoke fentanyl in the vehicle where Victim 1 rides.

A subsequent search of the residence allegedly revealed a plastic container with a white powder substance on a coffee table in the living room. Uselton reportedly claimed it was makeup, but the substance field-tested positive for cocaine. A digital scale with residue was also found under the coffee table. The complaint notes these items were within reach of Victim 1, a five-year-old child.

Both defendants are charged pursuant to Minnesota Statutes 152.025.2(a)(1) for the drug charges and 609.378.1(b)(1) for the child endangerment charges.
