Manner of death for two Michigan students undetermined.
WHITE RIVER TOWNSHIP, MICHIGAN (AP) -- Authorities say it's unclear whether the deaths of two Grand Valley State University students found inside a sport utility vehicle with two charcoal grills was an accident.
The Muskegon Chronicle reports a medical examiner this week listed the manner of death for 20-year-old Amber Rose Brown of Montague and 26-year-old Douglas William Ward of Aiken, S.C., as "undetermined."
Members of Brown's family found them dead Nov. 19 in a wooded area of Muskegon County's White River Township, about 50 miles northwest of Grand Rapids.
Carbon monoxide fumes from the grills were suspected in their deaths.
Investigators found the vehicle's interior vents covered with duct tape, and a camera included photos of the grills with hot embers.
Police say no further investigation is planned.
