Justin and Stephanie Shults, an American couple living in Belgium who had been missing since Tuesday’s terror attacks in Brussels, have died, family members confirmed on social media.

The couple were killed when a bomb exploded while they were saying goodbye to Stephanie Shults’ mother, Carolyn Moore, who was about to board a flight back to the United States, NBC News reported. Moore was not injured.

Justin, 30, and Stephanie, 29, both alumni of Vanderbilt University’s business school, moved to Brussels in 2014, and worked as accountants. Justin also attended the Nashville, Tennessee, university for his undergraduate education. The school released a statement mourning the pair and saying their global outlook represented “the very best of Vanderbilt.”
