Martinez Man Found Guilty Of Trying To Meet Minor For Sex

From the Office of the District Attorney, Contra Costa County:

On February 8, a Contra Costa County jury found defendant William Butte of Martinez guilty as charged of three felonies, including his attempt to meet a 15-year-old girl for sex. Butte, 50, communicated with who he thought was a minor on the mobile application Kik on August 24, 2017. Butte interacted with an undercover law enforcement officer after he posted a sexually explicit post on Craigslist, which contained language suggesting an interest in minors.

The undercover officer saw Butte’s Craigslist post in the now-defunct causal encounters section, in which Butte asked for a “naughty little girl” to engage in sex acts with him. During the conversation on Kik, Butte discussed meeting with the minor in-person, shared graphic details of sexual acts and he expressed a desire to have sex with the minor. When the undercover officer told Butte that he was a 15-year-old girl, Butte reacted favorably and asked questions about her sexual experience and history. Butte also invited the minor to his home to watch pornography together.

Butte and the officer discussed meeting in a public place. Upon Butte’s arrival to that agreed upon location, he was subsequently taken into custody and arrested.

Our Office will be requesting Butte serve time in state prison. Based upon the jury’s verdict, Defendant will be required to register as a sex offender pursuant to Penal Code section 290. Sentencing will occur on April 12, 2019 in front of the Honorable Anita Santos – Department 2 of the Contra Costa County Superior Court in Martinez. Contra Costa County Deputy District Attorney Adam Wilks prosecuted the case on behalf of the People. The case originated in the Office’s Sexual Assault Unit.

“Thanks in this case is due entirely to the jurors who sacrificed their time and had to wade through truly disturbing evidence in order to reach a fair verdict. Their service to the community in this case cannot be understated,” said Wilks.

The investigation was conducted by the Silicon Valley Internet Crimes Against Children Task Force, which is managed by the San Jose Police Department. In Contra Costa County, detectives and investigators from the Walnut Creek, Martinez, San Ramon, Concord and Moraga Police Departments, the Contra Costa County Sheriff’s Office, United States Secret Service, Homeland Security Investigations, the Contra Costa County Probation Department, and Inspectors from the Contra Costa County District Attorney’s Office participate in the task force.

Craigslist shut down the personal encounters section and the section is no longer active.

  • Count 1, Meeting Minor for Lewd Purposes
  • Count 2, Attempted Lewd Act Upon A Child
  • Count 3, Sending Harmful Matter to a Minor
