Court reveals alleged four-person mob behind fatal CTA Red Line push
Prosecutors told a court that four people acted together to push Kyle Bickham from a moving CTA Red Line train near 69th Street, killing him; 19-year-old Katlar Parchman is charged with first-degree murder and other felonies, the 15-year-old girl is in custody on murder charges, and two men remain at large; investigators say the suspects pulled the emergency lever and opened doors as the train moved; the defense contends the victim caused trouble, and Parchman remains detained ahead of a Tuesday court appearance.
