Now take that phone and hide under the passenger seat, in the tray.
After you find out where the swinematingslugeater parked it, go there and wait.
When he comes out to the car, call him, when he puts the altered phone to his ear, activate the 100,000 volt stun gun/phone, that he has pressed to his temple...
This should get his attention.
Oh,yea, if they ask you later... "He fell!"
