A man convicted of a "tidal wave of crime" that terrorized homeowners including "Lost" television series co-star Josh Holloway was sentenced yesterday to 13 to 30 years in prison.

Ruben E. Royce, 23, told Circuit Judge Karl Sakamoto that he was sorry for committing a series of home invasions in 2005 and 2006, saying he had a drug problem.

"I wish I could change it ... sorry," Royce said. "I wasn't in the right state of mind. I made mistakes."

Sakamoto, following the terms of a plea agreement worked out between the prosecution and defense, sentenced Royce to a mandatory minimum of 13 years and four months and a maximum of 30 years in prison.

Sakamoto told Royce he brought "a tidal wave of crime" on the community that "terrorized people in their own homes."

Senior Deputy Prosecutor Maurice Arrisgado said the final amount of time served by Royce will be determined by the Hawai'i Paroling Authority.

"We want the parole board, of course, to sentence him to 30," Arrisgado said.

He said all of Royce's victims agreed to the terms of the plea bargain.

Among Royce's victims were married couple Hisao and Kazuko Ishida, both in their 80s.

Royce broke into their home at 5 a.m., banged on their bedroom door and broke it open when the couple tried to hold it closed.

Kathleen Shota, the Ishidas' daughter, spoke at Royce's sentencing yesterday, saying her parents "are not the same" since the September 2005 attack.

Shota said her mother suffered an Achilles tendon injury and "didn't walk for five months."

She said her parents can no longer enjoy ordinary events in life like "going outside to get the mail" or "watering the yard."

Holloway did not testify but may appear before the Hawai'i Paroling Authority when it meets to determine Royce's prison sentence.

Royce admitted breaking into the Po'ipu Drive home of Holloway and his wife at 4 a.m. on Oct. 12, 2005. He threatened them with a loaded .45-caliber handgun and stole cash, credit cards and their Mercedes-Benz.

Royce has previously been convicted of two auto theft felonies.

He was represented by Deputy Public Defender Teri Marshall, who stressed to Sakamoto that Royce has taken responsibility for his crimes and has agreed to pay more than $4,000 in restitution to his victims.
