Eleven people were struck by a barrage of gunfire in the Marquette Park neighborhood late Sunday, leaving a woman dead in the second of two mass shootings of the night in Chicago, according to police.

       The attack happened in the 6300 block of South Artesian Avenue around 10:55 p.m., police said in a media notification. Of the 11 people who were hit, a woman whose name and age had not been released early Monday was the only fatality, officials said.

       The shooting was the second of two mass shooting attacks in the span of about two hours. At 8:45 p.m. six people were shot in the 2000 block of East 71st Street in South Shore. Between the two mass shootings, police said there had been at least 17 people shot, two of them fatally — one from each scene. A police spokeswoman would not say whether investigators think there is any connection between the two shootings or if they were unrelated.
