Officers spotted a possible suspect who fled into the Spartan Complex, the university's main athletics building.

The suspect, [23-year-old transient and parolee Joshua Castro](https://patch.com/california/campbell/gunman-firearm-seized-sj-state-placed-lockdown-police), hid in a third-floor ventilation system, where police [used a K-9 unit to locate him](https://www.kron4.com/news/san-jose-state-police-searching-for-possible-gunman/) and pepper spray while taking him into custody just after 8 PM. He was treated at a hospital for the pepper spray before being booked into Santa Clara County Jail.

    "The handgun was recovered across the street from campus, raising questions about whether the threat ever entered SJSU buildings"
