There are 5 Moura's Tear to be found in the game.
The first one you come to is during Chapter 1 - Talomera Del Rey
You will enter a room with executioner enemies, make your way through three of them ( don't forget to jump the chandelier for the 1UP!) drop down to the next level and on the wall to your left you will see a small cross, hit that a few times and the wall will be destroyed, jump in and claim your first Tear!
Make sure and grab it before dropping down to the bottom level with the barrels, you will have to start over if you do.
