A former girls basketball coach from Renton convicted nearly 10 years ago for sexual misconduct with a minor was sentenced Friday to nearly three years in prison for identity theft.

Anthony Derek Giles, 53, was sentenced in U.S. District Court in Seattle to 32 months in prison and three years of supervised release for aggravated identity theft and Social Security fraud.

An investigation this year by the Renton Police Department revealed that Giles was using the identity of a deceased infant to obtain employment and state benefits, according to a press release from the U.S. Attorney’s Office in Seattle.

Giles is a former elite basketball coach who was convicted in King County Superior Court of sexual misconduct with a minor. He was sentenced in 2003 to a prison term and was required to register as a sex offender.

According to records filed in the identity-theft case, in late 2009 the Washington State Department of Social and Health Services alerted the Social Security Administration Office of Inspector General that Giles was using the identity and Social Security number of a deceased infant, according to the press release.

Giles had used the identity since as early as 1990 to obtain drivers licenses and Social Security cards in the deceased child’s name. He used the identity for his employment at Boeing and to avoid revealing he was a Level III registered sex offender.

One of Giles’ attorneys, Neil M. Fox, wrote in an email that in regard to the identity-theft allegations, “it should be clear that investigators concluded that Mr. Giles did not receive any benefits under the other person’s name that he was not otherwise entitled to receive.”

Law enforcement had multiple contacts with Giles between 2008 and 2010, related to allegations of harassment and manufacturing marijuana, according to the press release. In executing a search warrant at Giles’ home in Renton, officers found photos and videos hidden in a stereo speaker box depicting Giles engaged in sexual activity with a 15-year-old victim.

Fox wrote in the e-mail that “Mr. Giles denies that the person in the video was under 18, much less 15. As we argued in court pleadings, the defense has never had the ability to contest the prosecutor’s allegations.”

In asking for a three-year prison sentence, Assistant U.S. Attorney Vince Lombardi wrote to the court that Giles “is a sexual predator with aberrant sexual interests…. (He) stole the identity of a deceased infant, and used it to obtain false identification. While he stole that identity well before his conviction for sexual misconduct with a minor, he continued to use that identity after that conviction to obtain benefits to which he was not entitled, and to avoid at least some of the consequences of being a registered sex offender.”

Fox wrote that the crimes for which Giles was sentenced Friday “hurt nobody.”

“While some may wish to use Mr. Giles’ personal problems as a means to revive the controversies of past decades, it is important to realize that the crimes for which Mr. Giles has been sentenced today hurt nobody. Like many people caught up in the criminal justice system, Mr. Giles has had difficulties finding employment,” wrote in the e-mail.

“In this case, Mr. Giles merely used a Social Security number that was assigned to him in the name of person who died decades earlier and he used this number so that he could get a job in commercial painting at job sites far away from minor children,” he wrote
