Deb Morgan died in the final season of Dexter after being shot in the abdomen by the serial killer Oliver Saxon. She was taken to the hospital and survived surgery initially, but complications arose when she developed a blood clot that caused her to slip into a coma and become brain dead. Dexter visited her in the hospital, and realizing she would never recover, he ultimately decided to take her off life support. Afterward, Dexter took Deb's body and secretly dumped it into the ocean, symbolizing her final rest. Her death was a tragic consequence of Dexter's failure to kill Saxon when he had the chance, which put Deb directly in harm's way.
