CHAMBERLAIN -- Three people from Minneapolis were arrested July 4 in Brule County after being found in a vehicle containing six pounds of marijuana, THC cartridges and edibles and two types of pills.

At about 10:30 a.m., a South Dakota Highway Patrol trooper was westbound on Interstate 90 near mile marker 259 when he reportedly observed a silver vehicle with a California license plate eastbound at 88 mph, according to court documents.

He pulled the vehicle over and identified 22-year-old Diamond Houston as the driver and Deondre Gunn, 25, and Darrell Webb, 31, as passengers.

The trooper brought Houston back to his patrol car and issued a warning for the speeding violation. When asked about her trip and why the vehicle might smell like marijuana, Houston reportedly said she and the two passengers were returning from a vacation in California and that there was a small amount of marijuana in the car.

A search of the vehicle was conducted and yielded six pounds of raw marijuana, 118 one-gram vape cartridges, 372 grams of THC shatter products and 40 packages of THC edibles, as well as a pill bottle in the driver's side door that allegedly contained 11 Xanax pills and 1.5 ecstasy pills. All three people were then placed under arrest.

Houston, Gunn and Webb are all charged with possession with intent to distribute one pound or more of marijuana, a Class 3 felony; possession of one to 10 pounds of marijuana and distribution or manufacture of a controlled substance in schedule I, both of which are Class 4 felonies; possession of a controlled drug or substance in schedule I, a Class 5 felony; and possession of drug paraphernalia, a Class 2 misdemeanor.

Because Houston had been sitting in the vehicle closest to the Xanax and ecstasy, she was additionally charged with possession of a controlled drug or substance in schedules I or II, a Class 5 felony, and unauthorized ingestion of a controlled drug or substance in schedule IV, a Class 6 felony.

If convicted of all charges, Houston could be sentenced to a maximum of about 47 years in prison, while Gunn and Webb could each face more than 40 years.
