"Identity Evil" is an in-depth look at a violent fake document cartel operating in states across the country. The cartel is the largest and most sophisticated fake id ring federal investigators have ever encountered. They were funneling millions of dollars from U.S. cities south of the border into Mexico. The cartel became synonymous with murder and torture as they sought to protect their turf from rival gangs and enforce discipline within their own organization. Using eyewitness accounts, federal wiretaps, and interviews with victim's families, investigative reporter A.J. Lagoe and photojournalist Ben Arnold take viewers inside the cartel and document the violence that would prove to be their undoing.
