This announcement was made during a special board meeting on Tuesday, May 17.

The school board voted to hire Varnum, a Grand Rapids-based law firm, and Guidepost Solutions, an independent investigations firm based in New York to conduct the independent review, the Detroit Free Press reported.

Attorney General Dana Nessel offered to conduct the review twice, which would save the school district the cost of an outside review, but the school district declined both offers and decided to have an outside firm conduct the review.
