A fourth teenager has been charged with first-degree murder in the beating death of a Chicago student who was walking home from school. Prosecutors announced charges tonight against 18-year-old Eugene Bailey, whose aunt has said her nephew didn't have anything to do with the beating that killed 16-year Derrion Albert on Thursday.
Prosecutors say the violence stemmed from a shooting early that morning involving two groups of students from different neighborhoods who then fought after school. They say Albert was a bystander and not part of either group. Three other teens were charged earlier Monday. (Read more Derrion Albert stories.)
