Quickly.They also found that JonBenet had sustained a very powerful blow to the head, which, though it did not cause external bleeding, caused intracerebral bleeding that would quickly prove fatal.
When someone's head is bludgeoned, it takes zero time to begin to bleed. Was JFK dead within a split second after he was struck with the fatal shot to his head? There was blood everywhere as his skull and brain shredded. When the doctors performed cardiac massage, they inadvertently and manually pumped more blood out through his head wound. If his heart and lungs were still working, more blood would have been pumped.
There is a bleeding and swelling and bruising that occur instantly when the vessels transporting blood are ruptured. Indeed, a cracking of the skull bone does not equal blood vessel damage. We do know, however, that Joni's brain bled, swelled and bruised from the massive blow she sustained. The force was so powerful, her living brain tissue ruptured upon impact. The blow was to the top of the skull/brain. That part of her brain controlling her heart and lungs was preserved and would continue to pump blood to the brain. Given this analysis, Dr. Wecht, a pro-RDI forensic pathologist, concluded that the presence of such a small volume of blood proved she was either dead or died very quickly after this blow. Her heart and lungs had stopped or would stop very soon after impact, from some other cause. Why? She was strangled first.
His pro-RDI theory on the cause of death eliminates the endless, convoluted, criss-crossed and wildly imaginative but hardly plausible conjecture that has led nowhere after all these years.
