SBCCD Police has cleared campus for reopening on Wednesday, December 16. Final exams will resume as scheduled on Wednesday.
Although San Bernardino Police determined the threat was a hoax within about 30 minutes (by approximately 6:00 p.m. PST on December 14), the campus remained closed all day on Tuesday, December 15, with the announcement of reopening made midday Tuesday, reflecting the extreme caution in the community following the December 2 mass shooting
Context

Background

The bomb threat at San Bernardino Valley College occurred in an atmosphere of intense fear and heightened security following the December 2, 2015 terrorist attack at the Inland Regional Center, which killed 14 people and injured 22 others just 12 days earlier. SBVC is located approximately 2 miles from the Inland Regional Center. The Washington Post reported that the college remained closed through December 15 even after police determined the bomb threat was not credible. The KTLA coverage noted that the San Bernardino Community College District Police conducted a thorough campus search before allowing reopening on December 16. The incident illustrates how community trauma from nearby mass violence events amplifies the impact of subsequent threats on educational institutions, particularly community colleges that serve local populations most directly affected by such events.
