In "Saw II" Michael was a police informant working for Detective Eric Matthews. He awoke with a spike-filled mask (called a "Venus flytrap" by Jigsaw) locked around his neck. A videotape and a set of x-ray slides revealed that the key had been surgically implanted behind his right eye, and in order to retrieve it he must remove his eye with a scalpel. He can not bring himself to do it, and when the timer expires the mask closes, killing him.
