Most Florencia (F13) also claim Sureño. Florencia is the second biggest Hispanic gang in L.A. and strongest in South Central Los Angeles. This area is located very close to the flashpoint of the L.A. Riots and the F13 were heavily involved in looting. The F-13 has a long running feud with the hated 18th Street gang with dozens of deaths attributed between these two major groups. Florencia and 18th Street have always been rivals but the situation got worse when the 18’s started a South Side clique around the late 80’s. F13 have beefed for years with the notorious 38th St. Gang of the “Sleepy Lagoon” Case. The F13 are heavily involved in drug dealing and have been courted by the EME for many years. F13 has been found in Mexico, and all over the West Coast, especially in Southern California, parts of Texas and Oregon, in Missouri, and have recently migrated to the East Coast. They are very active in Washington being found in Seattle/King County, Pierce County, Snohomish County, in Mt. Vernon, Othello, the Yakima Valley, and the Tri-Cities, WA, area.
In 2007, over (100) Florencia 13 gang members were named in a complex, three-year investigation named “Operation Joker’s Wild” The case looked into the gang’s activities in and around Huntington Park, CA, and other unincorporated areas south of Los Angeles. Mentioned as a catalyst in all the drama was EME/F13 shotcaller Arthur “Tablas” Castellanos who allegedly gave orders to Florencia gang members from Pelican Bay. U.S. Attorney Thomas P. O’Brien stated “The most disturbing aspect of the case is that in working to eradicate rival gangs from streets claimed by Florencia, gang members allegedly engaged in a series of attacks on rival African-American gangs that extended to innocent citizens who ended up being shot simply because of the color of their skin”. The main targets were East Coast Crips, a predominately Black gang who had a rivalry going back many years with the F13 gang over an alleged dope rip-off
