I I remember correctly the case was about this man and woman driving home one night and then some guy started following them, they drove around for a while trying to lose the guy but he still kept following them. Then finally they stopped the car and the man got out to go and confront the guy following them and then the follower killed the man? I think this is what happened. Does anyone have more info on this?

You got it--that is exactly what happened, and the victim's name was Dick Hansen. A search will bring up a number of threads about him. :)

They recon it was something to do with the girls licence plate.
Stupid really!
