• Mother and daughter die in accidental carbon monoxide incident

Authorities in Michigan have confirmed that a mother and her 16-year-old daughter died accidentally due to carbon monoxide poisoning after leaving their car running for several hours.

Kent City Police Chief, Sergeant Scott Dietrich, described the case as “unusual and rare,” noting that the SUV had been parked with the engine running long enough for carbon monoxide to accumulate inside.

The incident occurred on Tuesday, March 24, around 2:30 p.m. local time, at Maplewood Mobile Home Park in Byron Township, after police received a report of two unresponsive individuals inside a vehicle.

Responding officers found the mother and daughter deceased inside the SUV, with a strong smell of exhaust detected in the area. Authorities believe the pair may have been temporarily sleeping in the car due to circumstances at their residence, and that the vehicle’s exhaust system was in poor condition.

Tests later revealed carbon monoxide levels inside the car reached 2,000 parts per million within minutes of starting the engine—far above the 35 parts per million that triggers evacuations by fire crews.

The victims were later identified as Nicole Moore and Kelly Doig. Family members reported that they had returned from a trip to Tennessee that morning and had been resting in the car while discussing travel plans. Officials believe they may have been exposed to the lethal gas for an extended period before being discovered.
