Madison Hamburg was on a lunch break during film school on March 3, 2010, when the call came. “I was at Chik-fil-A with a bunch of friends, and my phone was broken that day. One of my best friends reached out to another friend, who was with me, to say my sister really needed to talk to me.” Hamburg’s younger sibling, Ali, had sent word that Madison shouldn’t call back until he was sitting down. “I thought she had gotten in trouble or something,” he told The Post. “And when I called, she said, ‘Mom’s dead.’ She was crying. She said, ‘Someone killed her.’ ”
