Sounds like there are two problems. One lead to the other.
1 - the likely reason the car won't shut off is because the ignition switch is bad.
2 - the likely reason for the grinding sound when the clutch is pushed in is a damaged piolit bearing.
My guess is that your friend is stopping the engine by popping the clutch. This will damage the clutch pressure plate fingers and piolit bearing -- he or she needs a new clutch and a new ignition switch.
