Question for everyone: If you were the first cop on the scene, would you watch the tape from the beginning, or just watch the end where he turns his brain into Alpo? Never mind, I know what your answer is!
No, he was instantly dead. That sound is called a "death rattle". Our lungs contain a certain volume of air that is never fully expelled when we breathe out. That sound Lopez makes is the final exhale of all the air in his lungs as the diaphragm completely relaxes, which it never does in a living person. It gurgles because a few milliseconds prior, he turned the entire inside of his head and sinuses into puree, and the air is burbling out through the liquid in his airway.
ooo i love the sound of that, 'death rattle'. sounds like a dangerous baby toy
