Former Army Officer Bruce Mendelsohn Helped Victims In the Aftermath of the Boston Bombings :    Former US Army officer Bruce Mendelsohn, 44, who served in the Persian Gulf War, was at a post-race party looking out the window at the Boston Marathon spectators when he heard the the explosions and sprang into action, pushing people to safety and assisting victims. He gave this first-person account of his experience to PEOPLE’s Nicole Weisensee Egan

On marathon day I was enjoying a post-race party with about two dozen people at an office right across from the finish line. At around 4:10 on the marathon clock I saw a flash from the corner of my eye; a blast wave immediately blew me off the couch upon which I was sitting and onto the floor.
