THREE RIVERS, Mich. -- Two Detroit residents are facing drug trafficking charges following a June 26 traffic stop by Detectives with the Southwest Enforcement Team.

Detectives then executed a search warrant at a motel room associated with one of the suspects.

In the motel room, authorities seized 48 grams of suspected crack cocaine, 20 grams of suspected diphenidine, and further evidence of drug distribution.

The suspects, a 33-year-old man and 42-year-old woman, were arrested and taken to the St. Joseph County Jail on felony Drug Possession and Trafficking charges.
