Ambulances from one West Side shooting flew by the scene of another as a weekend in Chicago began yet again with a burst of gun violence: An 11-year-old girl was killed, a 12-year-old girl wounded and more than a dozen other people were hurt over 12 hours.

Sirens drowned out the talk on Gladys Avenue just east of Pulaski Road where the 11-year-old was shot in the head during a sleepover. She was inside a home with friends when someone outside opened fire, sending a bullet through the walls into a room where the girl played with friends.

She was taken to Mount Sinai Hospital, where her family kept vigil until she was pronounced dead at 7:33 a.m.

She was the second child shot in the East Garfield Park neighborhood Friday. A 12-year-old was wounded in the 700 block of North Ridgeway Avenue about 3:30 p.m. along with two adults.

"It's just the way the young boys think out here," said David Jones, 44, as he stood on Gladys with his 2-year-old grandson. "Some get a kick outta hearing the gun go off."
