Liza Dmytriyeva, a 4-year-old with Down syndrome, is among at least 23 people killed in a Russian missile strike on the historic city of Vinnytsya in central Ukraine, authorities confirmed this weekend. “Sunny Flower,” as locals called the toddler, proudly pushed her baby carriage through a Ukraine park. She had just returned from the nearby speech therapy center, where she learned her first words. She liked to clean the corridor and helped to organize the toys there. She always seemed happy till a rocket took her life.
