Douglas John Fathke, 47, who has a history of mental illness, has said he does not remember shooting daughter Kelsie Marie Fathke with a .30-caliber rifle on April 20, 2003, at their Na'alehu home.

Circuit Judge Glenn Hara said Fathke represented an unpredictable threat to the community because Fathke had never exhibited that kind of violent behavior before, and the slaying was completely unexpected.

Hara imposed consecutive 20-year prison terms for manslaughter and the use of a firearm in commission of a felony, and another five-year consecutive sentence for terroristic threatening.

Kelsie Fathke's mother, Memarie Dhillon, traveled from Tacoma, Wash., to witness Fathke's sentencing, and heard Fathke tell the judge how sorry he is for the shooting.

"It's a little too late now," said Dhillon, 36. "No amount of years will ever be good enough. Whether it was 500 or 100, no amount will bring my daughter back, but it's good to know that he got the maximum amount allowed."

Defense attorney Brian De Lima said Fathke was experiencing delusions at the time of the killing, and has been taking medication that stabilized his mental condition.
