Thank you for some common sense. That website is usually just click bait speculation and this case is no different. First, no one said she was brain dead at the scene. Her lungs were probably scorched by the fire which would cause them to gradually fill with fluid, leading to hypoxia (lack of oxygen) even on a ventilator. Hypoxia leads to brain death. EMTs would cover her face if it was burned knowing that tabloids would love to have photos of a celebrity's burned face. She would try to remove the cover to breathe easier. If you want to kill someone, there are certainly more reliable ways than giving a person cocaine and a mini Cooper.
