A suspicious letter received at Dallas Sunset High School last week prompted a HAZMAT response Monday afternoon.
Dallas police were called to the school on the 2100-block of W. Jefferson Boulevard when an anry letter received last week was opened and found to contain a white powder.
Children at the school were moved to the back of the building, far from where the letter was opened and Jefferson was closed in front of the school.
Investigators were able to determine that the powder was, in fact, corn starch.
