Natalie was a ninth-grader at Laurel School, the all-girl private school in Shaker Heights. The school released a statement Monday morning after learning of her death. “'Our hearts are broken. Natalie came to Laurel in the Eighth Grade—a bookworm, scholar, and volleyball player, she was a gentle, warm, and thoughtful friend, looking forward with joy to Upper School,' said Ann V. Klotz, Head of Laurel School.  In the face of tragedy, the loss of a child is devastating, and the sudden and horrific loss of a family is excruciating. Our counseling team will be available to support our girls as the school processes its sorrow. The Laurel Community holds the extended Tobin family and Natalie’s friends in our hearts.”
