Jeremiah Hornbaker, who's known Frein through the film industry for nearly a decade, told ABC News that Frein was often hired as a military and weapons expert in films. Frein played the part of a German soldier in the 2007 short film, "Lustig," according to its IMDb page.
Bivens said Frein bounced between odd jobs and never stayed in one position for long. He belonged to a group of military simulation enthusiasts obsessed with Eastern Europe during the Cold War.
Police described Frein as a skilled shooter and a survivalist with a
grudge against law enforcement and authority.
