Marjory Stoneman Douglas High was locked down for nearly two hours Wednesday, exactly five years and one day after a gunman massacred 17 people at the Parkland, Fla., school.
The lockdown began around 1:50 p.m. and was lifted at 3:30 p.m., the South Florida Sun-Sentinel reported.
No credible threat was ever discovered, police said.
Students and residents in South Florida had solemnly marked the tragic anniversary Tuesday with events at multiple ceremonies.
Stoneman Douglas High was locked down after a suspicious phone call, according to local Fox affiliate WSVN. Broward County police described it as a “possible threat” to the school.
“The school has been placed on secure status as units investigate,” cops told the Miami Herald at the start of the incident. “No immediate threat has been identified at this time, and students and staff are safe.”
On Feb. 14, 2018, then 19-year-old Nikolas Cruz fatally shot 14 students and three staffers at the school. Cruz, a former Marjory Stoneman Douglas student, was sentenced to life in prison in November 2022.
In the years since the shooting, three students who were present that day have died by suicide. They were also honored at Tuesday’s ceremonies.
“The mental health impact this has on the students and parents can’t be explained in mere words,” said Rep. Jared Moskowitz (D-Fla.), whose district includes Parkland and Stoneman Douglas High.
