Two other vehicles were also stolen, WXYZ reported.
The car was found Monday morning, abandoned between two boarded-up homes, The Detroit News reported.
Police said it was found intact and with little damage.
"We believe the pressure of the media forced them to dump the vehicle," Sgt. Jonathan Parnell said.
Surveillance video captured the theft and police are examining the Camaro for any information who may have taken the car.
A lawn maintence man found the car in foot-high weeds.
"I said, 'Man, that looks like that Papa John's car,'" Ernest Webster told The Detroit News. "I looked inside and it was really clean. I called my brother-in-law, who is a cop, and he told me to call 911."
Watch when Schnatter re-purchased the Camaro in 2010.
