Margaret Roberts is a prize-winning investigative journalist and former news director of the hit crime TV show America’s Most Wanted. On the tenth anniversary of the Oklahoma City bombing, she answered a call from a grieving grandmother who lost two toddlers in the 1995 bombing that still stands as America’s deadliest domestic terror attack. 

It was the second time lightning struck Roberts' career and upended her life. As a rookie journalist in Chicago, she investigated a condemned prisoner’s plea and helped prove his innocence. Newsweek cited her investigation's “searing” effect on public opinion and policy. It also set the stage for Roberts to take on the extraordinary challenge to dig into the spiraling unsolved mystery of April 19, 1995 in Blowback.
