TUCSON, Ariz. — We're learning more about the recent school closings amid social media threats in Tucson this week.
Rumors on Snapchat of a possible threat prompted Pueblo High School in Tucson to go on a soft lockdown Tuesday.
Classes continued with Tucson Police and school safety officers on site, but TUSD says some parents chose to take their children home.
At a news conference Wednesday morning, TUSD Superintendent Gabriel Trujillo explained how the district determines what is a credible threat.
"If we don't have any hard evidence, if we don't have an identified perpetrator, if we don't have a suspect, if we can't verify that suspect has access to weapons, if we can't verify that there is an actual date and time, if we don't have witnesses that can corroborate the threat -- we don't want to be the kind of school district that's going to close everything down," he said.
Police arrested a suspect in connection with the threat Wednesday afternoon.
