BREMERTON, Wash. -- A Bremerton man confessed to killing his sister with an ax because they had argued and she made fun of him, police said.

Police arrested William Windsor Wednesday at an apartment where they found the body of 38-year-old Kimberly Shine with an ax in her head.

In a statement of probable cause, a detective said Windsor had been living with his sister since September, sharing a studio apartment.

Windsor said they argued about money for methamphetamine and she constantly belittled him and blamed him for everything, including cats making noise and waking her up.

Wednesday morning she was upset with him for wearing shorts because he didn't have any clean pants, he told police. He said he started crying because he was tired of her treatment and she mimicked him and made fun of him.

Windsor said he took an ax from a closet and hit her at least five times until the ax stuck in her head. He stopped because he couldn't remove the ax.

The coroner's office could not remove the ax and when the body was X-rayed it was embedded down to near the victim's jaw, according to police.

Windsor was jailed on murder charges. When asked about how he felt about killing his sister he told the detective, "What's done is done. I can't change it."
