Keely Vanacker, daughter of Fort Hood shooting victim Michael Cahill, says she is avoiding social media so she won’t see Nidal Hasan’s face as his scheduled execution brings back painful memories nearly 17 years after the massacre. Cahill was killed trying to stop Hasan during the 2009 attack that left 13 dead and 31 wounded. “I want to think about my dad. I miss my dad. I think about him every single day,” Vanacker said. ▻
