San Jose City College went into lockdown Tuesday evening after reports of a gunman on campus.

Officials canceled classes, the police closed Moorpark Ave. to traffic and some students and faculty were stuck inside buildings for two hours or more as police officers conducted a floor-by-floor and room-by-room search for the gunman.

They didn’t find one. No one was reported hurt or injured. And despite the disruption, classes will resume Wednesday on their regular schedule.

The hullabaloo followed a call placed to 911 around 4:30 p.m. warning of black male dressed in a white T-shirt and carrying a gun, according to police officials. The gunman was reportedly in the Technology Center, a building in the northwest side of the campus, which borders Moorpark.

College officials immediately sent out text and phone alerts to lock down the campus, said Dr. Rita Cepeda, chancellor of the San Jose/Evergreen Community College District. Although some parts of the campus were subsequently evacuated, the Technology building remained on lockdown until 7:30 p.m. while police searched the building looking for the gunman. College police officers were joined by San Jose Police in the search.

In the end, police neither found a gunman nor the person who reported the incident, Ray Aguirre, the college district’s police chief, said.

Percy Carr, the longtime coach of City College’s basketball team, said he spent the lockdown in the gym with 16 other people, including all the players on the team. The group wasn’t cleared to evacuate until around 6:40 p.m., after about an hour and half in lockdown.

The order to go into lockdown was initially unsettling to Carr and the team.

“In light of all the events that happened (recently), nobody was at ease about what was going on here,” he said. “We heard all the helicopters and saw all the red lights.”

But after a 30 minutes or so in lockdown, people started to relax, he said. “We felt safe,” he said.
