YAKIMA, Wash. — A convicted sex offender with a history of exploiting teenage girls was sentenced Wednesday to nearly five years in prison for failing to register.

It was Tommy Ashley’s third conviction for the same offense.

The 57-month sentence, handed down by Yakima County Superior Court Judge Ruth Reukauf, was at the top of the standard range for someone with Ashley’s criminal history.

Sheriff’s deputies arrested Ashley in January, saying he was not living at an East Valley trailer as he claimed in sex offender registration documents.

Ashley, 47, is classified as a moderate-risk, Level 2 sex offender. He has three convictions for crimes involving teenage girls.

The sentence was more time than he had served for two prior sex offenses, including a 1998 rape conviction for impregnating a 14-year-old girl.

In 2003, he was convicted of rendering criminal assistance and sentenced to 90 days in jail for his role in a manslaughter case involving a 16-year-old girl he was with at the time.

The girl was sentenced to eight years in prison for fatally bludgeoning a man with a beer bottle and stealing money from his wallet during a party. The age of consent in Washington is 16.
