WHITFIELD: All right, welcome back. We're learning more about the wife of an American diplomat accused of killing a teenage boy in a car accident while in the United Kingdom. The U.K. government now says that 42-year-old, Anne Sacoolas, does not have diplomatic immunity. And according to the British foreign secretary, the U.S. is also considering that immunity is no longer pertinent in this case. Police say that Sacoolas was driving on the wrong side of the road when she ran into 19-year-old, Harry Dunn, who was on a motorcycle. At first, Sacoolas told British authorities that she would stay in the country as police investigated. But then shortly thereafter, she returned home to the U.S. And now, Sacoolas could be extradited to the U.K. to face prosecution. An American gymnast, Simone Biles, has done it again. Today, the 22- year-old won back-to-back gold medals at the Artistic Gymnastics World Championship in Germany making her the most decorated gymnast in the tournament's history with a total of 25 career medals. Biles says she is now preparing for the 2020 Olympic Games in Tokyo, which she says will be her last. Amazing. All right. We all have our bucket lists, right? And this week CNN's "Hero" is helping senior citizens to embark on those exciting adventures this way.</s>WEBB WEIMAN, CNN HERO: The reality of living in isolation is out there and it's real.
