Hours after Destini Warren, 14, attended President Barack Obama’s speech against gun violence Friday, her family learned of a terrible irony. Destini’s sister, Janay McFarlane, 18, was the victim of the very thing that the President was condemning at Hyde Park Academy in Chicago. McFarlane, of the 8900 block of South Lowe Avenue, was visiting friends and family in North Chicago when she was shot on her way to a store in the northern suburb, her family said.
