Csi Dark Motives Please Help

[dylanis27]

Have tried everything possible to get an warrant for leslie the bike chick and to get warrant for cory but it aint happening.
Have done everything can think of but the only way can get an decent walkthrough is an PC one and not sure if the format is the same.
Have done the spring gone in close with it and looked at the v shaped cut etc got the swab of silicon of the throttle casing, matched every sort of finger prints possible and searched.
Have all parts from trailer and stunt scene in which theres dust on the floor but cant pick up anything.
What is there left to do please please help.

The PC says to match the prints together and then search it but get nothing but false names like HELEN OR KEVIN.
