'El Nicky', Cartel Assassin from San Luis Río Colorado, Sonora

“HEARST” for Borderland Beat

At 1:00 pm on May 10, 2021, authorities were alerted via a 911 call to the presence of an armed man and the sound of gunshots in the Residencias neighborhood of San Luis Río Colorado, Sonora.

Over the course of that day there had already been three “armed criminal operations” which had already left 2 dead in San Luis Río Colorado (SLRC). The description of the vehicle relayed to authorities was a 2006 black Jeep Cherokee SUV with Oregon, USA license plates.

According to newspaper Tribuna San Luis, Municipal Police with the support of the Mexican Army (SEDENA) surrounded a building on Hidalgo Avenue and 20th Street where a vehicle matching this description had been spotted. They set up a perimeter around the area and insisted those inside turn themselves in. After a few hours, authorities were able to arrest a 30 year old man identified as Ramón “N”.

Authorities executed a search of his vehicle. Inside the vehicle, they found three long barrel guns and a high-powered short barrel gun along with ballistic and tactical vests bearing the insignia CJNG [for "Jalisco New Generation Cartel in Spanish]. Some of the firearms found within the vehicle qualified as weapons for the exclusive use of the Army, so the man was able to be detained.

After he was detained, authorities were able to determine the man was Ramón Rosales González alias El Nicky, an alleged CJNG cartel member. El Nicky had an arrest warrant out for him in Mexicali, Baja California for attempted aggravated homicide. In addition, he was currently being investigated in relation to other Mexicali homicides, chief among them is a double homicide of two municipal officers.

The aforementioned double homicide of two municipal officers was also thought to involve two of El Nicky’s former associates, José Eduardo Pérez Jiménez alias El Charal and Jorge Humberto Maya Siqueiros alias El Vampiro.

Jorge Humberto Maya Siqueiros alias El Vampiro was recently killed in Mexicali on April 23, 2021 as previously covered on Borderland Beat after he was shot by rivals on a bridge that connects Mexicali and San Luis Río Colorado. El Vampiro managed to survive this attack but the ambulance transferring him to General Hospital of Mexicali the next day was shot up by two vehicles targeting El Vampiro. 

Meanwhile José Eduardo Pérez Jiménez alias El Charal was a hitman working in Vicente Martínez González alias El Guilo’s group in Mexicali. El Charal was killed December 15, 2019 by municipal police from SLRC.
