On the Northwest Side Sunday, a 7-year-old girl was killed and her sister, 6, was seriously wounded. More than 12 hours later, in predawn darkness Monday, a 70-year-old woman was fatally shot on the city’s Far South Side.

       They were the youngest and oldest homicide victims in a weekend that saw at least 55 people shot, six fatally, according to Chicago police and Tribune records. Most of the shootings happened Saturday afternoon into early Sunday. They included at least one attack with four victims and several each in which two or three people were wounded, officials said.

       The 70-year-old woman was shot in Hegewisch as she sat in her vehicle in the 13300 block of South Baltimore Avenue about 4:30 a.m. Monday. Two men approached her and opened fire, according to police.

       The woman began driving down the block, her vehicle coming to a stop after it hit a street sign, police said. She had been shot multiple times and was taken in critical condition to Advocate Christ Medical Center in Oak Lawn, where she later died.

       No arrests had been made in either of those homicides.
