FBI's Most Wanted

For the past four years, FBI agent Al Tribble has been hunting Alfonso Diaz-Juarez, a violent fugitive wanted for his alleged role in a multi-million dollar trafficking ring in Houston.

In 2015, three gunmen detonated a noxious gas inside an 18-wheeler carrying millions of dollars in gold bars. The Violent Crimes Task Force at the FBI's Miami's division is searching for the crew's ringleader, who still holds most of the stolen gold.
