A “secure and teach” lockdown at West Valley High School and nearby freshman campus on Tuesday was lifted after officials confirmed there was no active shooter on campus, the district said.

Yakima County Sheriff’s Lt. Aaron Wuitschick said a high school student who was not at school on Thursday received social media messages from students at school falsely claiming there was a shooter at the high school. The student called 911, and the Yakima County Sheriff’s Office, the Yakima Police Department and the West Valley Fire Department responded around 12:30 p.m.

Shortly before 1 p.m. officials verified that there was no active shooter, Superintendent Michael Brophy said.

Brophy said area schools were placed in secure and teach, a form of lockdown that allows teaching to continue, but limits movement on campus.

District communications director Anjerie Nemrow said this included the high school and freshman campus. Cottonwood Elementary School was in a “test only” drill, she said.

She said the secure and teach was lifted at the high school at 1:18 p.m., and was lifted at the freshman campus at roughly 1:30 p.m. A message was sent out to district parents to inform them of the incident.

“Officers did a sweep of the school and there was no active shooter. We are back to regular teaching,” Nemrow said of the high school.
