Lockdown Ends in Mabton, Grandview School Districts

A school lockdown situation is now over in the the Grandview and Mabton school districts. The incident began in Grandview when a student received a threatening text from her sister's boyfriend. The lockdown extended to Mabton because that is where boyfriend was believed to be. We have no word thus far on where boyfriend may be now. 
Students in Mabton tell us police were going classroom to classroom making sure no one who didn't belong was there
