Retired FBI Agent Frank Brostrom shares three of his wildest cases — going undercover as a hitman in a St. Louis murder-for-hire sting, tracking a fugitive who tried to ram his in-laws’ house with a gasoline-filled car bomb, and working the 1996 Atlanta Olympic bombing where quick action and a twist of fate saved lives.

From undercover stings to domestic terror investigations, these are the kinds of cases you don’t see in the movies.
