Stab-Rite - L.A. Noire

At Ray's Cafe, find the bloodstained knife on your first sweep of the crime scene - 15

This is done in "A Marriage Made in Heaven Case".

You will arrive at Ray's Cafe and sweep the crime scene for evidence, you need to go down the alleyway to the right of the cafe and search a bin, finding a bloodstained knife.

Later on in the mission, the coroner will call you over the radio saying that the murder victim was stabbed to death rather than run over. If you don't find the knife on the first sweep, you'll have to go back to the crime scene later on and find the knife, but this will void the achievement.

The word "rite" means religion, a body that is owned by the church or a religious practice; by that definition the word "stab-rite" a religious stabbing - this could a reference to the name of the case and the murder act which occured.
