Self-defense claim in Austin Metcalf slaying is 'uphill battle': expert

The 17-year-old charged in the stabbing death of high school track star Austin Metcalf will face an "uphill battle" if his attorneys present a self-defense claim in court, one expert says. 

Karmelo Anthony, 17, was arrested and charged with first-degree murder in Metcalf's April 2 killing at a track meet in Frisco, Texas. 

"If the evidence is what it is right now, I think he's going to have an uphill battle claiming self-defense," Julie Rendelman, a New York attorney who is not involved in the case, told Fox News Digital.
