SAN JOSE — The second victim of a daylight shooting a block away from San Jose State has died from his injuries as detectives continue searching for suspects, authorities said.

Police confirmed Thursday that a man critically wounded in the Tuesday afternoon shooting died at a local hospital. Another man riding with him in a van died shortly after the 2:11 p.m. attack on South 11th Street between East San Antonio and East San Carlos streets.

The latest victim marks the city’s 25th homicide of the year. Neither victim in Tuesday’s shooting has been publicly identified while authorities notify their next of kin.

Officers were called to the area Tuesday for reports of a shooting and found two men suffering from gunshot wounds inside a van that had been shot at multiple times, according to San Jose police. Both men were rushed to the hospital, where one was pronounced dead soon after.

A gray van was spotted fleeing the scene. Neither a motive nor suspects have been officially identified, but a source familiar with the investigation told this newspaper that detectives are exploring whether gang motives fueled the attack.

The shooting rattled the surrounding neighborhood, which features a mix of family homes and student housing.

A nearby resident was moving into the Pi Kappa Alpha fraternity house when he heard gunshots. While he did not see the actual shooting, he said he heard a car accelerate quickly and looked out his window onto 11th Street to see a van meandering forward, with a motionless driver slumped inside.

SJSU interim President Sue Martin said in a statement that she was “deeply shaken” by the homicide that “occurred in a neighborhood where many students and other members of the SJSU community live or regularly walk.”

With 25 homicides to date this year — compared with 10 by the same point in 2015 — San Jose is on pace to record one of its highest homicide totals in 25 years. But San Jose police warned against reading into that figure as a reflection of public safety in the city, noting that domestic violence, a case of self-defense and a co-worker conflict comprised over a third of those killings.
