It's nice to be back with you this weekend. On the program tonight we'll have the latest on the air disaster in Russia that has claimed the lives of Poland's president, along with his wife and several top Polish government officials.
We also have details on the discovery overnight of the remaining four miners who were victims of this week's explosion in West Virginia.
Many us are still trying to make sense of the case of a Tennessee woman who sent the 7-year-old boy she adopted from Russia, back to his home country -- aboard a plane by himself -- after she became unable to cope with his behavior. Ron Allen has made his way to the mother's Tennessee community to find out more about her and how her neighbors are reacting.
Thanks for checking in. We'll look for you tonight on NBC Nightly News.
