Anyone ever had an issue with the starter motor continuing to crank after the ignition switch is off?

Here is the deal.

Start the car runs fine.
Turn off the car starter continues to crank.
disconnect the battery and the starter stops.
Reconnect the battery and it is fine until you cycle the key again.
We took out the ignition switch and jumped the wiring. same issue.
New starter solenoid in. Same issue.

Any ideas?
