A former Pearl City man was sentenced in U.S. District Court on Wednesday to 29 years and two months in prison for producing images of a minor boy engaged in sexually explicit conduct and making the images available on the Internet. 

U.S. District Judge Derrick K. Watson also ordered that Ray K. Yokoyama, 54, register as a sex offender, and undergo a lifetime of supervised release following his prison term. 

Watson said Yokoyama was previously convicted of impersonating a law enforcement officer, and failed to accept responsibility for his conduct. 

Yokoyama has been detained at the Federal Detention Center since his arrest on Jan. 18, 2013. 

U.S. Attorney Florence T. Nakakuni said that according to information in court, Yokoyama produced child pornography using a minor on two occasions in 2009, distributed child pornography over an Internet file-sharing network in July 2012 and possessed child pornography in January 2013. 

According to an FBI affidavit filed in 2013, the investigation was started after an undercover agent in Dallas downloaded child pornography from a computer in Hawaii. 

Agents traced the computer to Yokoyama’s home in Pearl City, and executed a search warrant for the residence. Agents recovered computer storage media, including a disk that contained images of a minor boy engaged in sexually explicit conduct. 

In court proceedings, Yokoyama admitted taking pictures of a minor boy engaged in sexually explicit conduct. According to information provided in court, the boy was approximately 9 years old at the time.
