FILE – This undated photo provided by Eric Paddock shows his brother, Las Vegas gunman Stephen Paddock. On Sunday, Oct. 1, 2017, Stephen Paddock opened fire on the Route 91 Harvest festival killing dozens and wounding hundreds. Paddock left behind little clues about what led him to carry out the deadliest mass shooting in modern U.S. history. He killed 58 and wounded nearly 500 before killing himself. 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 neurological problems. (Courtesy of Eric Paddock via AP, File)
