Letter from the district:
Dear HPISD Parents & Staff,
Highland Park High School dismissed students at 11 a.m. today after a threatening note was found on campus.
Parents whose students need transportation may pick up their children at the multipurpose facility across from Highlander Stadium.
HPISD leaders will continue to work with police to investigate the threat. Last month, three similar notes were found at HPHS.
Parents, please talk with your children about how seriously any threats, written or otherwise, are taken on campus.
We will continue to keep you informed.
The school has been evacuated at least four times in recent months; no legitimate threat has ever been found.
