They are not giving out details of the "prank".
No arrests have been reported.
The wife is pretty p!ssed off over it. Benbrook is a school where teachers are not allowed to carry. All they did was put the school on lockdown and told the employees nothing else. She is a diagnostician on contract with them, and previously spent 10 years working in Texas juvenile justice facilities with violent offenders. But, she says she has never been so scared as she was this morning because FWISD put her in a position where she was trapped and not allowed to defend herself if there really was an active shooter. (Aside from her education credentials, she is also a Texas concealed-carry instructor.)
