Former Dolphins offensive lineman Jonathan Martin posted a chilling Instagram story that forced a high school to close. Martin became the victimized face of NFL bullying in 2013 when he charged teammates, namely fellow offensive lineman Richie Incognito, with harsh treatment in the locker room. On Thursday, he posted an Instagram story that featured a photo of a shotgun and the handles of Incognito, another former teammate Mike Pouncey and the Los-Angeles area high school, Harvard-Westlake, that Martin attended. “When you’re a bully victim and a coward, your options are suicide or revenge,” Martin cryptically posted. The post comes a week after 17 students were killed at Florida’s Stoneman Douglas High School.
