CHICAGO --Security was increased Wednesday at a high school on Chicago's South Side after gunfire rang out near the school. It happened less than a block from Morgan Park High School in the 1700 block of West Pryor. No one was hurt. But school officials sent additional security and police to the school. The gunfire comes just one day after a former Morgan Park student was killed nearby. Eighteen-year-old James Bush was fatally shot Tuesday night. Police say the shooting may be gang related.
