Families Say 4 Americans Are Missing From Brussels Airport

Four Americans believed to have been at the Brussels airport on Tuesday remain missing more than 24 hours after the deadly terrorist attack there, according to their families. Married couple Justin and Stephanie Shults, from Tennessee and Kentucky, respectively, moved to Brussels for work in 2014, the AP reports. According to NBC News, they had just dropped Stephanie's visiting mother off at the airport when two suitcase bombs exploded. The couple hasn't appeared on any casualty lists so far, but their phones are going straight to voicemail. Stephanie's cousin says the family is currently hoping the pair are simply busy helping people, "which is very much their nature."

Siblings Sascha and Alexander Pinczowski from New York are also missing, the New York Daily News reports. They were at the Brussels airport Tuesday speaking with a relative on the phone when the relative heard an explosion and lost the connection. Family has since been unable to reach them. Family and friends of the Shultses were briefly given false hope when Justin's brother Levi Sutton tweeted that they had been found. The State Department announced that was incorrect and asked Sutton to delete his tweet. "I apologize for the misinformation that was given to my family," NBC quotes Sutton.
