Stephen Paddock's brain is being sent to Stanford University for a months-long examination after a visual inspection during an autopsy found no abnormalities, Las Vegas authorities said. Doctors will perform multiple forensic analyses, including an exam of the 64-year-old's brain tissue to find any possible neurological problems. Dr. Hannes Vogel, Stanford University Medical Center's director of neuropathology, would not discuss the procedure with The Associated Press and referred questions to officials in Clark County, where Las Vegas is located. Authorities have resorted to putting up billboards in southern Nevada seeking tips and now the intensive brain study that medical experts say likely won't yield definitive answers. Experts say the brain study on Paddock will be a worthy effort for scientific reasons.
