Emeryville Cop Resigned After Probe Found He Lied About Interactions With Sex Workers

A former Emeryville police officer resigned in 2014 after investigators found he had improper interactions with sex workers and was dishonest when questioned about those interactions, records released late Thursday show.

Documents reveal that a woman working as a confidential informant for investigators told them that former officer Joshua Patterson asked another sex worker to "secure a 14-year-old female for sex."

Police Secrets Revealed

The informant told investigators that she heard two other sex workers talking about Patterson and one told the other, "Patterson likes her but wants a younger girl to join them," and to set up an encounter at a Motel 6. The informant said that the juvenile couldn't be found, and the planned encounter never happened, according to the documents.

Patterson could not be reached for comment. The attorney who represented him in his disciplinary proceeding didn't return a message Thursday. Emeryville Police Chief Jennifer Tejada also did not return messages.

In one instance, which appears to have been part of a "sting" designed to catch Patterson, documents show that while on duty he picked up a sex worker who was cooperating with police and drove her around in his patrol vehicle. An investigator wrote that he was able to hear over a “cellphone wire” as Patterson asked how much she would charge him for sex, according to the documents.

She responded "$60, but $50 for you and $40" for oral sex. But Patterson didn't go through with the act, saying he didn't want to take off his uniform in case a call came in.


Patterson "was not truthful in many of his responses" when questioned about his relationships with multiple sex workers, Michael Fraser, a consultant Emeryville hired to conduct its internal affairs investigation of the officer, wrote in a report. Sometimes Patterson claimed he couldn't remember encounters with the women. Other times, he changed his story while being questioned.

Eventually, Patterson was found to have violated a dozen department policies, but investigators could not prove he had sex with prostitutes while on duty. None of the women admitted having sex with him, but some said others did.

Patterson is the latest cop to have sexual misconduct detailed in documents released under Senate Bill 1421, the state's new police transparency law that requires the release of serious misconduct information. Other records released under the new law show officers in Burlingame, Watsonville and other departments fired for sexual exploitation.

Patterson joined the Emeryville Police Department in January 2012 after working as an officer in Draper, Utah, for two years. He was accused there in a 2010 federal lawsuit of throwing a man to the ground who "suffered contusions and gashes, a concussion, bleeding in his brain, additional head injuries, and a separated shoulder," according to court documents. Draper police declined to comment Thursday night. The lawsuit was eventually settled.

Documents show an extensive investigation of Patterson, including tracing him to an area in Oakland called "The Triangle," which is known to be frequented by sex workers.

Data from a tracking device on his police vehicle showed Patterson spent a significant portion of his available on-duty time outside the jurisdiction of the Emeryville Police Department — specifically in an area of northwestern Oakland, near the border of Emeryville and Berkeley, known for prostitution.

Records also show Patterson was found to have committed multiple violations of department policy in two separate incidents. They include improperly handcuffing a person, not reporting other use-of-force incidents and not reporting unspecified criminal activity.

A November 2011 Emeryville City Council memo shows the Police Department spent about $900 to send an officer to Utah to complete a background investigation into Patterson, calling him “one of the top candidates" to become a police officer in the city. The trip was needed because Draper police refused to send Patterson's personnel file to California.
