A sordid story that brought unwelcome national attention to Jamestown came to a close today when Nushawn Williams was sent to prison for at least four years for knowingly exposing a young woman to the AIDS virus.

Williams, 22, who Chautauqua County authorities said infected 13 young women with the HIV virus after he arrived from New York City, was sentenced by County Judge John T. Ward to a term of 4 to 12 years.

Williams pleaded guilty Feb. 26 to two counts of sodomy for having sexual intercourse with a 13-year-old girl in 1996 and a single count of reckless endangerment. The girl is now infected with HIV.

Chautauqua County District Attorney James P. Subjack declined to comment after today's proceedings but previously has said he feels the Williams case demonstrates glaring weaknesses in the laws dealing with HIV victims.

Williams is due in court in New York City Thursday for sentencing on a reckless-endangerment charge for spreading the AIDS virus to a 15-year-old girl in the Bronx.
