Missing Graduation Cap

In search of graduation cap, last seen on May 4, 2019

I am a graduating student who has misplaced her graduation cap, it was last seen at the Howard Performing Arts Center on May 4, 2019. It is a black graduation cap with a white tassel with the Andrews University official seal on the tassle. I have retraced my steps with no posiitive outcome. I will be departing campus before Friday, May 10. Please, if anyone has located the cap on or off campus, please contact me as soon as possible, my number is (914) 258-4527. Many thanks!
