Earlier Thursday, the parents of Karmelo Anthony, a 17-year-old teenager who is facing a murder charge in connection to the stabbing, had spoken publicly about the case for the first time. Jeff Metcalf, Austin’s father, was barred from attending the news conference.

The father of the Frisco ISD teen who was fatally stabbed at a track meet earlier this month made an unexpected appearance where his accused killer's parents spoke on Thursday.
