The Case
After a dinner party, Diane found a deep scratch on her car's front-left fender. Five cars were parked single-file in a narrow driveway: Yvonne (deepest), Hank, Diane, Carter, and Brooke (closest to street). The scratch appeared sometime during the party. Case file HARD-023.
Whose car scratched Diane's?
Evidence (7)
#1The scratch on Diane's car is on the front-left fender, consistent with a sideswipe from a car on her left side.
#2The driveway is single-lane. Cars parked in order: Yvonne, Hank, Diane, Carter, Brooke (street-side).
#3Nobody left during the party. But Brooke moved her car to let a delivery truck pass at 7:30 PM.
#4Brooke's car has a fresh scrape on its rear-right bumper. The paint residue matches Diane's car color.
#5Hank's car shows no damage. Yvonne's car was deeper in the driveway and couldn't have reached Diane's front.
#6Carter's car is parked behind Diane (between Diane and Brooke). No damage on Carter's vehicle.
#7The delivery truck driver says Brooke backed up quickly to make space.
