After infecting at least 13 women with the HIV virus, a New York sex offender may be jailed indefinitely, according to The Associated Press. The attorney general’s office said Nushawn Williams should face lifelong imprisonment under a civil law created to shield the public from the most notorious perpetrators.

Under a statute, the state can imprison a sex offender indefinitely if it proves the person is likely to commit additional crimes. If he is found mentally unstable, Williams would be held at a medium-security psychiatric facility.

Court papers describe Williams, 33, as a mentally disturbed drug dealer who at times was violent during his 12-year prison stay. He pleaded guilty in 1998 to charges of statutory rape and reckless endangerment after word of his HIV status created an uproar in Jamestown, N.Y. Nicknamed “Face,” Williams often engaged in sexual acts with drug-addicted women and girls as young as 13.
