MOLINE, ILL. – Past midnight Saturday, the Quad City International Airport was deserted and silent as a cleaning woman wiped the Delta ticketing counter.
"All kinds of rumors," she said, shaking her head. "Everybody is wondering."
What happened to Prince here in a middle-of-the-night medical emergency landing just days before he died? Did it prefigure his subsequent collapse inside Paisley Park?
Those questions have made this city the unlikely center of a mystery riveting the world's attention.
Situated along the Mississippi River with a population of 44,000, Moline was founded on the riverboat trade but is best known now for the corporate headquarters of John Deere. Located 165 miles west of Chicago and 360 miles southeast of Minneapolis, it also sits underneath busy air corridors.
And with no other large runways nearby, it's not uncommon for Quad City International to become an emergency destination for flights diverted for medical reasons, said Jeff Patterson, the airport public safety manager/police and fire chief.
Just after 1:15 a.m. on April 15, Prince's private plane became the latest coming in for a surprise landing, according to federal aviation records.
On the ground, an emergency call came in for an "unresponsive individual," airport Human Resources Manager Jo Johnson confirmed Saturday.
