A man who pleaded guilty in Fairfax County Circuit Court to abusing his niece 16 years ago, was sentenced yesterday to 10 years of probation.

Francis R. Wilkie, 65, who now lives in Salem, Ore., was sentenced to the maximum of five years in prison on each of two counts of taking indecent liberties with a minor and the maximum three years' imprisonment on one charge of sodomy, but those sentences were suspended by Judge Jack B. Stevens.

The judge also ordered Wilkie to pay therapy costs for his 27-year-old niece, Laura White, and perform 1,000 hours of community service, said his attorney, Peter D. Greenspun.

Wilkie was convicted last month after pleading guilty to two assaults on his niece, which occurred in 1971 and 1974.

White, who consented to the use of her name by the media, brought charges, she said, after years of counseling helped her realize she was not responsible for the abuse, which she said occurred from the time she was 4 until she was 13.

Wilkie, a former English teacher at Chantilly High School, was indicted in May in Fairfax County. Greenspun said Wilkie will be allowed to transfer his probation to Oregon.
