OVS (Ontario Varrio Sur and also known as Onterio Varrio Sunkist) is a Mexican American (Chicano) gang from Ontario, California.

The gang consists of approximately 2500+ members and two sub-cliques known as the Junior Black Angels and Black Angels. OVS began as a car club in the 1950s and gradually split into two rival cliques, the Black Angels and the Earth Angels.

One of the most notorious crimes associated with OVS was the June 22, 1987 murder of Mary Lou Davila-Salazar, her boyfriend, and roommate. Arrested for the murder was recently released parolee and OVS gang member Ruben "Tupie" Hernandez. Hernandez murdered Davila in retaliation for her role in the recent murder of fellow gang member "Tito" Marines. Hernandez was convicted in the late 1980s and sentenced to three consecutive life sentences in a California prison. During the mid 1990s (circa 1994/1995) and after the death of Mexican Mafia "EME" leader Joe "Peg Leg" Morgan, OVS (BA-Sunkist) member Ruben "Tupie" Hernandez assumed the leadership role of the Mexican Mafia, while housed in Pelican Bay State prison.


OVS has a long history of involvement with the Mexican Mafia.

OVS gang colors are black and white. Their dress attire includes Baltimore Orioles hats, using the "O" to represent Ontario.

Criminal activity

Community hero and Ontario Police Detective Brice Devey serves as a veteran officer with the Ontario Gang unit with many years of experience working with the OVS gang. He clearly states that the primary activity of the OVS gang is murder. Along with repeated activities such as robberies, assaults and narcotics sales. This information is also based on his personal experiences and certified documents with his many years with the O.P.D. Gang unit.

OVS is notorious for their participation in hate crimes against African Americans in their neighborhoods. OVS main source of income is from illegal narcotics and gun trafficking. OVS, as with most other Sureño gangs, are well connected with Mexican drug cartels, specifically the Sinaloa cartel. Methamphetamine, cocaine, black-tar heroin, and marijuana are sold by street dealers who operate out of numerous hidden "trap-houses" where the product is stored and processed into smaller quantities. OVS also sells arsenals of illegal/stolen firearms, ranging from handguns to assault rifles, as well as knives, clubs, and other weapons.



The OVS Earth Angels are formed, with their original territory starting in south Ontario.

June 2001

In June 2001, Hector "Pirate" Ruben Lopez was a suspected OVS Black Angels member, with an outstanding warrant for his arrest. On June 20, 2001, Glen Willett, then a Senior Special Agent of the California Department of Corrections, received information that Lopez was located at a residence on Oakland Avenue, in Ontario, California. During surveillance, Willett and Ontario Police Department ("OPD") officers observed Lopez's mother and brother, Joe "Joker" Martel, enter the Oakland Avenue residence. Martel was a known OVS Black Angel gang member who was also on parole. Through a window in the door, Willett saw Lopez "peek around the corner from a hallway. Willett ordered Lopez to open the door, but Lopez disappeared down the hallway out of sight. A few minutes after Willett and the OPD officers unsuccessfully tried to force entry, Lopez opened the door and was arrested a few feet outside the front door. The officers conducted a protective sweep of the residence, forcing entry into a back bedroom. In the hallway bathroom toilet, officers found an empty clear plastic baggy. After the residence was secured, the officers conducted a parole search of the residence. During the parole search, officers found plastic baggies containing methamphetamine and three handguns.

On June 27, 2001, Bureau of Alcohol, Tobacco, Firearms, and Explosives Special Agent David Silva requested federal prosecution of Lopez. Behnke accepted the case for prosecution pending further investigation, and opened a case file for Lopez on July 5, 2001.

In late September 2001, FBI Special Agent Volk interviewed Lopez, for a second time, about Lopez's knowledge of the OVS Black Angels, and advised Lopez that he "could be looking at serious federal time" unless he cooperated. Lopez refused to cooperate. Lopez was thereafter indicted by a federal grand jury for being a felon in knowing possession of firearms, in violation of 18 U.S.C. § 924(c), and for possession of methamphetamine with intent to distribute.

Lopez pled guilty to possession of methamphetamine with intent to distribute, reserving the right to appeal the denial of his motions to dismiss and suppress. Lopez was sentenced to 169 months in prison.

February 20, 2015

OVS gang members Carlos "Chino" Rivera, Raul "Crook" Prieto, and Jessica Medina attempts to appeal their jury convictions arising out of activities connected with the OVS Black Angels, Prieto objects to the admission of testimony from Black Angels gang leader David Navarro regarding the meaning of the term "bird" and argues that the prosecution mischaracterized Navarro's testimony in its closing argument. However, Navarro's testimony was admissible as a lay opinion supported by his experience as the leader of the gang's extortion activities and participation in methamphetamine sales. The evidence is sufficient to allow a rational fact finder to convict Prieto based on the distribution of methamphetamine. The recorded telephone calls demonstrate Prieto's willingness to sell half an ounce of a larger supply of a controlled substance. Prieto never questioned Rivera regarding what type of drugs Rivera was expecting when he "re-upped," allowing for a reasonable inference that Prieto understood Rivera's reference. This inference is bolstered by Navarro's testimony that Rivera had conducted methamphetamine deals from Prieto's mother's house in Prieto's presence and with Prieto's knowledge, demonstrating that Prieto knew that Rivera trafficked in methamphetamine. Finally, Rivera was arrested with nearly half a pound of high-purity methamphetamine following his conversation with Prieto. Because a conviction can be proven through circumstantial evidence and inferences drawn from that evidence, and because a reasonable fact finder could conclude that Prieto knew Rivera was distributing methamphetamine and that Prieto was requesting half an ounce of methamphetamine to sell. Prieto's argument failed.

High ranking members

Tupi Hernandez

A veteran of OVS (Sunkist St-Black Angels), Tupi joined La Eme during one of the frequent trips behind bars he made during his late teens. Tupi, along with his best friend Tito Marines, led OVS in battle against other well-established surrounding gangs.

Tupi's devotion and eagerness to please his superiors in La Eme led him to become known as one of the most dangerous inmates in the California prison system – a designation he would prove when his buddy Marines was killed while he served an 8-year sentence for robbery. Upon his release, Tupi promptly returned to his old haunts where he chastised the younger members of OVS for failing to take care of business, meaning kill a list of people he had passed down through the "prison information network" before his release. Prime on his list of people to kill was Mary Lou Davila Salazar, the woman he deemed responsible for Marines' murder. During a series of meetings with the most promising Eme recruits from OVS, Tupi warned the youngsters to stay off of the street Salazar lived on, and secured an arsenal of weapons to complete his mission of revenge. In an event which shocked the city of Ontario, Tupi entered Salazar's house on the morning of June 22, 1987 and savagely beat and executed not only Salazar, but also her young roommate and her boyfriend.

Darryl "Dashing D" Castrejon

One of the top leaders of the OVS family and one of the Mexican Mafia top leaders in California, Darryl Castrejon's leadership and influence as an enforcer has spawned a new breed of generational top notched soldiers and new recruits for La Eme throughout California.
