The driver fled, went through a red light, and led police on a chase, the Clinton County Sheriff's Office said in a news release.
During that chase, the sheriff's office received a call from Thornburg claiming she left her keys in her car, and that it had been stolen. The vehicle, she said, was a 1998 grey Buick Century — the same car the deputy was pursuing.
Thornburg allegedly drove into neighboring Scott County, where police tried and failed to use Stop Sticks — a device used to deflate tires. Iowa State Patrol, however, had better luck with the device, and was able to stop the pursuit less than an hour later.
Authorities took the driver into custody and identified her as the caller who reported her own car missing while leading police on a multi-county chase.
Thornburg was charged with eluding, driving with a suspended license, reckless driving, and speeding.
