We are all shocked and saddened by the unexpected passing of Bianca Avitia, a kindergarten teacher at Jonathan Burr Elementary School. Our thoughts and prayers are with her family during this difficult time. Over her teaching career, Ms. Avitia gave selflessly to the City of Chicago and our children. In the days, weeks and months ahead, we should all rely on each other to continue the critical work of educating our children to which Ms. Avitia was so dedicated.
