EVERETT, Wash. -

A Seattle police detective who earlier pleaded guilty to cyberstalking-domestic violence has been sentenced to 90 days in jail for posting sexually explicit photographs of a woman after she ended an extramarital affair with him.

The Seattle Times reports that prosecutors say 44-year-old David Blackmer vowed to "ruin" the woman's life after she went to his Snohomish County home last July to tell his wife about the affair.

He was also ordered yesterday to pay a $1,000 fine and avoid contact with the victim for five years.

He will be allowed to carry a gun.

The Seattle Police Department's Office of Professional Accountability will now begin a separate administrative investigation into the detective's conduct.

Blackmer has been on leave.
