The Shield Wiki

Diagur Leyva was one of the leaders of the Byz Lats.

The Byzantine Latinos (or Byz Lats) were a Latino gang operating in Farmington.

Before Season 3[]

At some point, the Byz Lats planned to take control of the drug trade in Farmington. To achieve this, their leader - Garza - made a deal with a military officer called Lex to purchase illegal weapons and prepare for a gang war with the One-Niners.

After the weapons were delivered, Diagur Leyva, a soldier from the Byz Lats, convinced his father to serve as courier for a shipment of ammunition from Yuma, Arizona. After picking it up, he headed back to Los Angeles.

Season 3[]

On his way back to Farmington, Jesse had an accident with a teenage drug dealer, which led the Strike Team to find out about the shipment of ammunition. During his interrogation, Jesse refused to implicate his son Diagur.

Vic Mackey and the Strike Team went to an arcade place where Diagur and the Byz Lats hung out and threatened them if he found out they were arming themselves. Despite this, the Byz Lats killed a One-Niners soldier called Slap in a drive-by shooting.

As retaliation, Kern Little shoot at some Byz Lats gang members when they were hanging on the street.
