A woman was pulled over for speeding...

When the officer reaches the vehicle he informs the woman that she was driving more than double the speed limit and asks to see her license and registration. The woman refuses to produce them and, when asked why, states that she doesn't have a license or registration and that the vehicle is stolen.
Taken aback the officer asks her to open the trunk and step out of the vehicle. Again the woman refuses and tells the officer that she can't open the trunk because inside is the dead body of the vehicle's rightful owner, who she killed earlier that day.
Completely flabbergasted, the officer tears open her door, pulls her out of the car, cuffs her, and hauls her to the back seat of his cruiser. He then calls dispatch and asks for backup and a forensic team to join him at the scene.
Once the forensic team arrives they open the trunk of the woman's car and find nothing. No body, no blood. They search the car top to bottom and find the vehicle registration in the car's glove box and the woman's license in her purse, both matching her identity. A second officer who is now on the scene retrieves the woman from the cruiser, sits her on the curb, and begins to question her.
"Ma'am, do you own this car?"
"Yes sir"
"You didn't steal this car, kill the owner, and stuff them in the trunk?"
"No sir"
"This officer told me that you refused to produce your license and registration and that you stole this car and killed the owner."
"I'll bet he told you I was speeding too, didn't he."
