The 15-year-old accused in a school shooting at Marshall County High School in Kentucky that killed two students and left 18 others injured appeared today in juvenile court. The judge found probable cause to detain him on preliminary charges of murder and assault. Assistant Marshall County Attorney Jason Darnall said he can’t comment on what happens inside juvenile court, where the teenager’s identity and details of the crime remain cloaked in secrecy. But he reiterated that the state wants to try the teenager as an adult. Meanwhile, authorities are gathering evidence for a grand jury, hoping to discover why he fired into a crowd of his classmates, all 14 to 18 years old, as they waited for the morning bell inside Marshall County High School this past Tuesday.
