Investigators have solved the case of a mysterious smoking bag found aboard a plane flying out of the Moline airport.
Investigators say they found nothing suspicious in the bag.
They add that first responders must have seen and reported the residue of the airplane's fire suppression system.
The bag was discovered in the cargo area of the American Eagle plane, filled with smoke, when it landed at the Dallas Fort Worth International Airport back in January.
