He was the primary cause of an HIV micro-epidemic in Chautauqua County. He infected at least 14 women in Chautauqua County with HIV, including numerous teenagers. In 1999, he pleaded guilty to two counts of statutory rape (two of his victims were underage) and one count of reckless endangerment in the first degree for having unprotected sex with a woman who did not know his HIV status. He received a four-to-12-year sentence. Two of Williams' children in Chautauqua County were born with HIV, raising the number of known cases linked to Williams to 16. Many of these women continued to have unprotected sex after their diagnosis, spreading the disease to new boyfriends. An additional 10 of Williams's sexual partners in New York City have been found to be HIV-positive, though it is unclear if Williams is the source of these infections, since New York’s population makes it harder to track.
