An Oahu jury deliberated a little more than a day before finding the operator of a portable toilet rental company in Nanakuli guilty yesterday of sexually assaulting a 15-year-old boy who worked for him.

The jurors found Henry Moisa, 58, guilty of three counts of first-degree sexual assault. The jury deadlocked on a fourth first-degree sexual assault charge.

Moisa, who operates A's Party Portables, faces a mandatory 20-year prison term when he is sentenced in July. He remains free on $250,000 bail.

Circuit Judge Glenn Kim denied the state's request to increase Moisa's bail to $2.5 million following the jury verdict.

The boy told police Moisa performed oral sex on him in 2007 and 2008. He said the first time was when he started working for A's Party Portables in May 2007. The boy was 14 years old at the time.

Deputy Prosecutor Adrian Dhakhwa said the boy was shocked at first but later consented because Moisa paid him for the sex.

The boy told his friend he earned $1.25 for every toilet he cleaned and $5 side money every time he let Moisa perform oral sex on him.

State law prohibits having sex with minors under 16 by persons who are at least five years older and not married to the minor.
