Activists have called for prosecutors to investigate the stabbing of a 24-year-old black man outside a Pittsburgh bar as a hate crime after video emerged of the white suspect using a racial epithet.

Joden Rocco has been charged with homicide in the death of Dulane Cameron Jr. Police allege he had just been ejected from Tequila Cowboy around 2 a.m. Sunday when he started a confrontation with Cameron and Cameron's friend, who also is black, on a sidewalk. The men scuffled and police said Rocco stabbed Cameron in the neck and fled.
