What began as a dispute over a seat at a Texas high school track meet ended in tragedy when one 17-year-old student allegedly pulled a knife and fatally stabbed another — all at a school neither teen attended.

The organization Next Generation Action Network held a press briefing on Thursday to address the case, including threats the family said they have received.

A lawyer for 17-year-old Karmelo Anthony says his legal team is trying to get his $1 million bond lowered. Fundraisers have drawn hundreds of thousands of dollars for him.
