HOUGHTON — Two Detroit men were arraigned in 97th District Court Friday on charges related to heroin distribution.

Kellen Werdlow, 33, and Johnathon Knuckles, 28, were arrested Thursday after a one-month-long Upper Peninsula Substance Enforcement Team investigation on charges related to possession with intent to deliver heroin, a 20-year felony.

UPSET detectives had developed information that the suspects had been bringing in large quantities of heroin to sell in Houghton County for several months, UPSET said in a news release Friday. Detectives determined the suspects were traveling to Houghton County from Detroit Thursday. The Michigan State Police Hometown Security Team conducted a traffic stop near Atlantic Mine after the suspects left a residence in a vehicle.

UPSET detectives executed a search warrant at the residence at the same time of the traffic stop and seized seven grams of heroin with a street value of $1,700, UPSET said. Initial testing of the drugs indicated a presence of a fentanyl compound in the heroin. During the search of the vehicle and passengers, troopers recovered approximately $3,800 in cash and numerous cell phones and other drug paraphernalia.

Bond was set at $100,000 cash for Werdlow and $150,000 cash for Knuckles.

UPSET was assisted by MSP-Hometown Security Team, Houghton County Sheriff’s Office and Superior Service.
