Tips pour in on slain girl, 15
CHICAGO - Chicago police say they have been inundated with tips about the death of a 15-year-old girl who had just returned from performing at President Obama's inauguration, but police, activists, and ministers are still concerned that someone with valuable information might be holding out.
The reward for information about last week's slaying of Hadiya Pendleton has climbed to $40,000. But people may be afraid to come forward because they don't want to be thrust into the national media spotlight or because they are concerned for their own safety, police, activists, and ministers said.
Pendleton, a drum majorette, was killed in a park about a mile from Obama's home on the South Side.Police say the shooter hopped a fence, ran at a group of about a dozen young people, and opened fire. No arrests have been made. - AP
