Betro initially fled the scene but returned by taxi just after midnight and fired three shots at the family home. By 13:30 BST, she was at Manchester Airport and flew to the US, prosecutors said. Days later, Nazir followed and according to Betro, the pair rented a car and drove to Seattle "just for a road trip" with stops at an amusement park, Area 51 in Nevada, Los Angeles and San Francisco. She told jurors she did not know there had been a shooting in Measham Grove and Nazir had not mentioned it during his time in the States. The investigation to find Betro and bring her co-conspirators to justice not only spanned several years but was hampered by the pandemic and involved the FBI, National Crime Agency and two UK police forces.

Breast cancer affects way too many of us. In the US, one in eight women will develop it in their lifetimes. But encouraging new research shows that artificial intelligence can help with early detection. An AI system developed by Google Health, Google-owned DeepMind, and several medical centers is so good at detecting breast cancer that it can outperform actual doctors, according to a paper published this week in the journal Nature. The AI analyzes mammograms -- the X-rays commonly used to check for breast cancer -- to determine whether the disease is present. Researchers found that the AI system reduced false positives by 5.7 percent for US women -- a significant improvement, when you consider how distressing it would be to be told you have cancer when you actually do not.
