From obsessed former lovers to unrelenting acquaintances fueled by the thrill of the chase, stalkers can have a range of motivations, but all instill a perpetual fear within their victims. With over three million people falling victim to stalking in the United States each year, this widely misunderstood crime reaches far beyond celebrities and people in the public eye. "Stalked: Someone's Watching" profiles six emotional stories of stalking victims and explores the twisted psychology of the people who relentlessly pursued them. As the first president to issue a National Stalking Awareness Month proclamation, President Obama in January 2011 helped focus national attention on this serious crime and stressed the challenges in recognizing and combating stalking. In recognition of National Stalking Awareness Month, Stalked: Someone's Watching premieres on Monday, January 24 at 10:30 p.m. ET on Investigation Discovery, America's leading investigation network and the fastest growing network in television.
