CHICAGO (AP) -- Chicago Police say they are receiving many tips as they investigate last week's shooting death of a 15-year-old high school majorette. But there is also a concern that people with valuable information may not be coming forward.
Some say people may be reluctant because they don't want to get caught up in a case that made national headlines. Hadiya Pendleton was killed weeks after performing at some of President Barack Obama's inauguration festivities in Washington D.C.
Others wonder if people are staying silent out of concern that talking might put their own lives in danger. The gunman is believed to be involved with gangs.
There is a $40,000 reward and police say they remain confident that they will make an arrest in a case.
