A former Burbank High School track and cross-country star has been charged with murder after allegedly fatally stabbing a first-grade teacher and critically injuring her daughter in their Burbank home.

Sergio Fraire, 30, was taken into custody Monday night after a SWAT team served a search warrant at an apartment building on East Palm Avenue in Burbank. He pleaded not guilty to the charges Thursday and is being held without bail.
