Investigation concludes with arrests

A two-month investigation led to drug-related charges against four people this week.
Members of the St. Joseph County Area Narcotics unit made the arrests late Tuesday following the execution of a search warrant at a residence in the 300 block of West West Street in Sturgis.
Police said investigators discovered a considerable amount of heroin, methamphetamine and items used to package drugs.
Two 50-year-old Sturgis residents – a man and a woman – were arrested. In addition, two Kalamazoo residents – a 23-year-old man and 19-year-old woman – were taken into custody.
All four face charges of delivery of heroin, conspiracy to deliver heroin, possession with intent to deliver heroin, possession with intent to deliver methamphetamine, possession of marijuana, maintaining a drug house and frequenting a drug house, according to authorities.
