Help William Grose Walk at Graduation

Hi, my name is Jenn Smith and my son William Grose just finished high school at Kalkaska High school. We are looking for help with paying for a football jersey that the school lost and now in order for my son to walk with his class we have to pay400 bucks for the missing jersey. They are missing one jersey but he has to pay for 3 jerseys. It is not fair that a child that returned his stuff now has to pay for a jersey the School lost. Any help would be great his graduation is on May 22.
