MARQUETTE — Police say the cause of death in relation to the two bodies found in late October in a home along Sherman Street in Marquette was due to an apparent drug overdose.

Marquette City Police Department Detective Lt. Greg Kinonen said there is currently no cause for public concern and that the investigation is still ongoing.

On the morning of Oct. 21, officers were dispatched to a duplex at 911 Sherman St. where they discovered the bodies of 31-year-old Adel Renee Winter and 29-year-old Mark Alan Bibler II.

Their deaths were initially classified as “natural” in the department’s police log from the day of the incident. Police explained this classification is used when the cause of death is unknown upon arrival to the scene.

“Obviously, we brought in the state police to process the scene,” Marquette Police Chief Blake Rieboldt said in a previous interview with The Mining Journal. “There was no evidence at the scene indicating any major crime like homicide or a suicide or anything like that. We’ve taken all the steps that we can to ensure that the scene was processed correctly and safely.”

Marquette police were assisted on scene by UP Health System EMS, the Marquette City Fire Department, Michigan State Police Crime Lab and Northern Michigan University Police Department.
