HONOLULU -- Prosecutors asked the Hawaii Paroling Authority Board on March 3 to keep Kirk Lankford behind bars for 120 years; the board gave him 150 years.

A Circuit Court judge convicted Lankford for the 2007 killing of Japanese national Masumi Watanabe.

During the trial, Lankford claimed he slightly injured Watanabe with his truck on the North Shore, that she fell and hit her head on a rock and then he tossed her body into the ocean because he did not want to lose his job.

Watanabe's family and prosecutors said she was sexually assaulted and beaten to death.

"This is an exceptionally long minimum term and it's very justly deserved because of the callousness of the defendant that was not only apparent to the jury, but also apparent to the paroling authority," Honolulu Prosecutor Peter Carlisle said.

Defense attorney Don Wilkerson said 150 years is a long time for a second-degree attempted murder conviction.

Wilkerson said he plans to appeal Friday's decision. He is already appealing Lankford's conviction.

In a statement, Hawaii Paroling Authority Chairman Al Tufono said, "Mr. Lankford's behavior after the victim died displayed a high degree of coldness and callousness."

Under current parole guidelines, Lankford, 24, must spend one-third of his term or 50 behind bars before he can ask for a reduction in his minimum term.

His defense lawyer was livid.

"If you're going to put a man in jail for 150 years, you better damn well come up with the evidence and the documentation to do it," Wilkerson said.

During the parole hearing, prosecutors detailed other allegations against Lankford, that he sexually assaulted another Japanese national, that he abused his wife and that he tortured and killed cats. The parole board gave his lawyer until Friday to respond in writing and his lawyer drafted a 50-page response to the allegations which he turned in yesterday. However, the board actually signed its decision Wednesday, so it never read his attorney's filing.

"The parole board dishonestly failed to give Mr. Lankford the opportunity to respond and listen to what he had to say," Wilkerson said.

A parole board spokesman said the board received a letter from Lankford himself on Tuesday, they said they thought that was all that was going to be filed on his behalf.

Prosecutors were able to tell Watanabe's parents shortly after the ruling.

"We immediately got in contact with the family in Japan. Mrs. Watanabe was so overcome that she was in tears of joy. So, it's been a terrific result. Everyone has done their job correctly," Carlisle said.
