A 26-year-old man was sentenced to 20 years in prison on Tuesday for setting fire to a Kailua home over a dispute about work done to the house.

Ozane Alexander Mosley Jr. was also sentenced to a minimum term of 6 years and 8 months by Circuit Court Judge Rom Trader.

“I made a lot of stupid decisions,” Mosley said in court before he was sentenced. “I’m sorry for me being a burden to everybody.”

Mosley of Kapolei, pleaded guilty to first-degree arson in April.

He set fire to the vacant Kailua home on May 17, 2013 at about 10:30 p.m.

Deputy prosecutor Ronson Ibarra asked the judge for an extended sentence of life in prison with the possibility of parole and a mandatory minimum of 6 years and 8 months because Mosley qualified as a repeat offender.

Deputy Public Defender Steven Nichols asked the judge to deny the extended sentence, saying the mandatory 20-year prison term and his burns are punishment enough. According to Nichols, Mosley was burned on a majority of his body, including his arms, legs, and upper torso in the fire.

Trader granted the mandatory minimum, but denied the extended sentence.

Police said Mosley was identified by tissue, blood and human skin found after the fire was extinguished. Vapors from a liquid accelerant caused an explosion when Mosley lit the fluid, police said.

Mosley was treated for burns the night of the fire, but told police the burns were from a cigarette he had lit after refueling his girlfriend’s car.

API Corp, a real estate company that owns the home, said there was a dispute with the contractor, Honolulu Home improvement, which is run by Mosley’s family, a police statement said. The real estate company had withheld final payment of $2,500 because it believed the remodeling work was sub-standard and needed to be corrected.

The DNA profile obtained from the samples matched Mosley, whose information was on file because he is a convicted offender, police said.
