DALLAS — In May, John Park received one of the worst calls of his life.
Park, a physician in New York, picked up the phone and heard screaming on the other end. It was his mother back home in Texas. Panicked, she told him she had been shot.
“I thought that that was going to be her last moment,” Park said. “I literally thought that would be the last moment that I speak to her, so I was tremendously terrified.”
