Booze Bottles are Not Clues
Do not waste your time on things like cigarette butts, booze bottles and other things. They are solely meant to throw you off as you investigate a crime scene.
Avoid Criticism While Driving
If you are tired of listening to your partner criticize your driving, simply leave him and do not give him a chance to get in the car as you take off. He will appear when you arrive at the destination.
Red Dead Redemption Reference
In the Silk Stock Murder, after you investigate the long blood trail leading onto the roof, examine the body and find all the clues. You will be returned to your car. Instead of leaving, turn around and investigate the alley behind you. You will find a trash can with a cowboy hat in it, which Red Dead Redemption players may recognize as belonging to one John Marston.
