Contra Costa County occupies the northern portion of the East Bay region of the San Francisco Bay Area, California. It is primarily suburban, and has a population of over 1,100,000 residents. Its county seat is Martinez. Commercial sex activity has been well-documented in the communities, and in unincorporated areas of the county. This activity and the problems and ancillary crimes it generates results in complaints to law enforcement agencies from residents and businesses. Among the more serious crimes associated with the local commercial sex market is sex trafficking, and violence committed against both the providers and consumers.

Consumer level demand provides the revenue stream for all prostitution and sex trafficking, and has therefore been targeted by local law enforcement agencies as a strategy for prevention and response. The Contra Costa Sheriff’s Department often collaborates with municipal police departments to conduct reverse stings. For example, in Bay Point (formerly West Pittsburg) complaints about prostitution from residents and businesses, as well as homicides involving prostituted women, encouraged the Contra Costa County Sheriff’s Office to adopt new strategies that target sex buyers in addition to sex sellers, and have conducted a street-level reverse sting operations to arrest buyers.

Pittsburg is located near Bay Point, Antioch, Concord, and Walnut Creek. Prostitution and sex trafficking have been identified as problems in all five communities, including the presence of  a serial killer who targeted sex sellers in the 1990s. In their efforts to reduce prostitution, the Contra Costa County Sheriff’s Office and Pittsburg Police Department have conducted periodic reverse stings since at least 1998. Operations are typically conducted at street level, using one or more female undercover officers as decoys. The names of arrested male sex byers are not routinely released to the public. In 1998, media outlets reported that county officials were considering adopting an auto seizure ordinance that would enable them to seize and impound vehicles used for the purposes of solicitation. It is unclear if said ordinance was ultimately adopted. However, the city of Richmond, CA, enforces vehicle seizure as a demand reduction tactic under Chapter 11.94 – Vehicle Seizure and Forfeiture.* 

The Richmond Police Department began conducting street-level reverse stings in 2005, and web-based reverse stings in 2008. Once arrested, male sex buyers in Richmond may have their vehicles seized (if they were used for the purposes of solicitation) and may have their driver’s licenses suspended. If convicted, they may be served with SOAP orders that restrict their ability to enter areas of the city known for prostitution. In March 2014, the RPD announced that it would also use its Facebook and Twitter pages to broadcast the identities of arrested sex buyers; in September 2014, the names and arrest photos of 11 sex buyers were posted to the department’s Facebook page following a sting operation. In October 2018, a reverse sting on 23rd Street yielded arrests of eight sex buyers and the rescue of two juvenile girls ages 15 and 17. Residents and city officials have also undertaken efforts to address demand prior to the point of arrest, by engaging in public education campaigns and developing neighborhood watch groups. In 2014, Richmond Police reported to members of the local media that had been working with “residents in the area of 23rd Street and lower Ohio Avenue to report the license plate of anyone they suspect is loitering for the purpose of soliciting a prostitute. The owner of the vehicle is then sent a ‘Dear John’ letter that notifies them they were seen loitering in an area known for prostitution.”

County-wide efforts are usually led by the Sheriff’s Department.  E.g., in  March of 2017, a retired Oakland police captain was sentenced to jail, probation and a “john school” prostitution awareness class after he admitted to buying sex from a young woman at the center of a Bay Area police sex exploitation scandal. A Contra Costa Superior Court judge sentenced the man to two years probation and five days in jail, and he was allowed to substitute “court watch” for jail time, meaning he can serve his sentence simply by sitting in a court audience. Additionally, he was required to pay approximately $1,200 to attend a “john school” program. “Dozens” of current and former officers were investigated after the woman told investigators she’d engaged in commercial sex with officers from numerous Bay Area police agencies, including some who she said gave her inside information about upcoming prostitution stings. Further, she alleged that in a few instances, she was underage. The investigation implicated officers from Oakland, Livermore, Richmond, the Alameda and Contra Costa Sheriff’s Departments, amongst other local agencies. It led to lawsuits against the cities of Oakland and Richmond. Four Richmond officers were implicated in the scandal, out of 11 who were investigated, and three were fired. Additionally, a former sheriff’s deputy from Contra Cost Sheriff’s Department resigned from his position as a result of being accused of soliciting the woman when she was a minor for sex. in September of 2016, the former Contra Costa Sheriff’s deputy and two Oakland police officers were charged with felony offenses of sexually exploiting a minor.

The county has also participated in statewide collaborations with demand reduction components. For example, in February, 2020 the results from the statewide “Operation Reclaim and Rebuild” were announced. The week-long operation was led by the Los Angeles Regional Human Trafficking Task Force and 70 participating federal, state and local law enforcement agencies (including the Contra Costa County Sheriff’s Office) and task forces from across California. In addition to rescuing and assisting victims of sex trafficking and human trafficking in addition to arresting and subsequently prosecuting the sex traffickers, Operation Reclaim and Rebuild also seeks to disrupt the demand for vulnerable victims by targeting sex buyers. Investigators focused enforcement operations in situations where sex trafficking took place, which included street-level and internet-based operations. The operation deployed specially trained cyber detectives who posed as vulnerable teenagers and interacted with suspects on social media, sex traffickers and sex buyers who sought to sexually exploit and abuse children. Operation Reclaim and Rebuild resulted in the arrest of 266 male sex buyers for the charge of Solicitation, 27 suspected sex traffickers, as well as the rescue of 76 adult and 11 juvenile victims. In the press release announcing these results, the head of the Task Force said, “To the Johns:  Purchasing commercial sex is illegal and buying sex adds to the exploitation of those involved.”

In March, 2023, a former Deer Valley High School employee in Antioch faced felony charges for allegedly arranging to meet minors for transactional sexual acts, and authorities were asking for the public’s help in tracking down other potential victims. The Contra Costa County District Attorney’s office said the former teach faced multiple felonies following his March 16 arrest in a sting operation. The investigation began in 2022, just days after he started a job as a deputy campus counselor at the school. A parent of a student reported to school officials that the man sent the student inappropriate text messages about marijuana use at school, as well as sexually suggestive messages. In a statement, the superintendent of the Antioch Unified School District said the suspect had worked a total of seven days at the school when the report was made. The county’s Internet Crimes Against Children Task Force (ICAC) took up the case to see if the suspect would sell marijuana to a minor and arrange for sex. Investigators posed as a 13-year-old girl on a chat app and the man allegedly offered to sell the fictional teen marijuana as the chats became more sexual in nature. On March 16, the suspect arranged to meet the teen for sex at a park in the city of Martinez, and when he arrived he was arrested by members of the ICAC task force and then incarcerated at the Martinez detention facility. He was charged on March 21 with seven felonies, including contacting a minor for a sex offense, showing a minor pornography, meeting a minor for lewd purposes, and attempting to supply marijuana to a minor to sell. ICAC Senior Inspector said the man may have been in contact with other victims and urged anyone with information about the case to email him.  A preliminary hearing was scheduled, and the Contra Costa Superior Court website shows that the man was held on $405,000 bail.
