SAN JOSE -- Authorities have identified a 15-year-old boy as the victim of a deadly shooting in June that capped a massive street brawl where combatants wielded baseball bats and shovels, all within line of sight of Happy Hollow zoo.

Delfino Guerro, of San Jose, died the night of June 12 in the courtyard of an apartment complex near South 12th Street just north of Keyes Street, near Spartan Stadium. He was formally identified Tuesday by San Jose police, who did not explain the delay in releasing his name.

Police were called about 10:20 p.m. that night for reports of a fight in the street involving as many as a dozen people. Witnesses said some of those involved used baseball bats and shovels taken from a nearby work truck.

Amid the melee, gunshots were fired, police said. Witnesses said the victim was running either from or with other people into the courtyard of the apartment complex when another shot was fired. Delfino was pronounced dead at the scene.

The killing marked the city's 19th homicide of the year. While the neighborhood is known to experience gang activity, a motive has not been determined and the case remains unsolved.
