A Kauai man is scheduled for arraignment in state court in Lihue this afternoon on sexual assault charges involving minors.

A Kauai grand jury returned an indictment last month charging Michael Terui, 37, of Lihue, with five counts of third-degree sexual assault involving two boys.

Three of the counts accuse Terui of molesting one boy between 2014 and 2017, when the boy was younger than 14 years old. The other two accuse Terui of molesting another boy, once between 2008 and 2011, before the boy turned 14, and again in 2011 after the boy turned 14.

The grand jury had indicted Terui in February on two counts of sexual assault involving a third boy. The charges accuse Terui of molesting the boy in 2014 and 2015, when the boy was younger than 14.

He is also scheduled to stand trial in U.S. District Court in October on federal charges of producing child pornography.

Kauai police started investigating Terui in January after the boy identified in the earlier indictment reported that Terui had sexually assaulted him. Police said at the time there could be additional victims.

Police later revealed that Terui told them he had molested and recorded seven minors over the past eight or nine years, including those mentioned in the charges.

They said Terui told them he molested and recorded two boys and two girls between the ages of 7 and 13 in 2016. They said he also told them that most of the sexual assaults happened in his home and that some victims might not know what happened to them because he molested and recorded them while they were sleeping.

The federal child pornography charges stem from images the FBI recovered from electronic devices Kauai police seized from Terui’s Kaneka Street home.

Terui’s lawyer has filed papers in state and federal courts seeking to exclude any of the search warrant evidence.
