(BREITBART) — by Robert Arce
Residents in the border state of Sonora are bracing for another wave of violence as factions of the Sinaloa and Beltran Leyva Cartels continue fighting for control of lucrative drug smuggling territories.
For months, the Sinaloa Cartel faction called Los Salazar have been fighting with rivals in the Beltran Leyva Cartel, previously led by Trinidad “Chapo Trini” Olivas Valenzuela. The fighting has focused in the municipality of Cajeme and particularly in the border city Obregon.
This month, Olivas Valenzuela was gunned down in the coastal state of Jalisco as he ate near a food truck.
In the days leading up to the murder of El Chapo Trini, the municipality of Cajeme saw a series of warnings disseminated through social media to residents about impending violence. The message warned locals to avoid being outside after 6 p.m. because they could come upon a shootout. The message was allegedly signed by two commanders with the Los Salazars identifying themselves only as El 75 and El Pirata.
