Stephen Paddock's autopsy reveals no brain abnormalities
Vegas shooter Stephen Paddock's brain autopsy results have been revealed. County Sheriff Joseph Lombardo announced the mass killer's brain revealed no abnormalities, but investigators were still waiting on his body's toxicology report. There are still no clues to why the lone gunman committed the worst mass shooting in United States history. Kevin McMahill of the Las Vegas Metro Police Department told ABC News: Paddock's girlfriend, Marilou Danley, told investigators she was not worried about his mental health. She has since been cleared from having any involvement in the attack.
