ELI5: why do some burn victims die months after being exposed to the fire?

I was reading about some burn victims from summer fires in Greece, and some succumbed to their burns more than 3 months after they were originally exposed to the flames. Shouldn’t they be in the clear at that point given burn wounds heal over time?

Burn icu nurse-
Think of the skin as being the largest organ in your body. Damage to the largest organ will inevitably have an impact on other organs. The first organs that start to go are the kidneys. Think of how your skin retains moisture in your body. It keeps the water in your blood. Your blood becomes thicker now without as much water in it. Your kidneys filters your blood. Your heart pumps your blood.  Now you have nothing to keep that water in . Your thickened blood is more susceptible to clot. Cause a stroke or a clot in your lung. We try to keep blood flowing to all our organs to deliver oxygen to them. We divert this blood to the most important areas- our brain, our heart.  Everything works harder in your body. Your lungs work harder to put oxygen in the blood. Your gut doesn’t get enough blood flow, and not enough oxygen. The tissue starts to die. It starts to breakdown with your stool in it and spread infection inside your body.  And of course the obvious answer that’s mentioned above is the large amount of open skin is highly susceptible to infection.
