On the afternoon of Sunday, June 11, a 29-year-old finance lawyer named Wisam Naoum stopped at a gas station to stock up on beer. It was a sunny, hot afternoon, approaching 90 degrees, and Naoum had a leisurely day planned at his sister’s backyard pool. Earlier that morning he had heard rumblings of trouble in his community, but nothing was confirmed, and Naoum was wary of unverified rumors, so he kept his plans with his sister and her family.
