Update: July 20th
A New York Supreme Court judge in Buffalo has dismissed Nushawn Williams’s  petition for release and ruled he could remain in jail while awaiting his  October trial under New York’s Civil Confinement Law.
Update: May 11th
No big surprise, but a New York State Supreme Court judge has ruled that Nushawn Williams “poses a  danger to society and as a result, must remain behind bars even though  his sentence is complete.”
State Supreme Court Justice John Michalski said there is probable  cause that Williams suffers from a “sexual abnormality” that would pose a  danger to society.  
With the ruling, Williams could now face a trial to determine his  future status.
Both sides are due back in court next month as they hold arguments  over a defense motion to dismiss the case.
Under a civil law, passed in 2007, the state can lock up a sex offender indefinitely if it proves the person has a mental abnormality and is likely to offend again.

The impact of the 1997 Nushawn Williams case continues to reverberate in New York.  Following last year’s denied request for parole, there are now plans to keep him locked up forever by New York’s Attorney General Andrew M.  Cuomo.
The New York Times reported on April 13th
Mr. Williams, 33, was due to be released on Tuesday after serving his  maximum sentence of 12 years, but Mr. Cuomo’s office is seeking to keep  him in custody under a three-year-old state law that permits the civil  confinement of sex offenders. Last Friday, a state judge in Buffalo,  near where Mr. Williams has been jailed, ordered that he remain in  custody pending the outcome of a civil confinement proceeding.
Now, State Senator Cathy Young of Olean is not only urging Cuomo to keep Williams in civil confinement but also proposing a new HIV-specific law for New York using Williams as a “poster child”.  Back in February 2009, Suffolk County District Attorney Thomas Spota teamed up with Parents for Megan’s Law to advocate for the same thing.
Here is Senator Young’s press release, featuring her proposed law in full.
Senator Cathy Young  (R,I,C – Olean) today renewed her   call for a law making it a crime to  knowingly spread the deadly   HIV/AIDS virus to other unsuspecting  people. Senator   Young’s announcement comes in the wake of news that  Nushawn   Williams, the man who caused an AIDS epidemic in Chautauqua    County in the 1990s, had completed his prison sentence and could   be  released to the public. 
   Senator Young also called on  New York State Attorney General   Andrew Cuomo to rigorously fight to  ensure that Williams remains   confined in a psychiatric facility and is  not let back out into   the community. 
   “People who  knowingly use HIV/AIDS as a deadly weapon   by purposely exposing others  to the disease should be severely   punished. This proposed law would  provide the appropriate   penalties for those who callously put other  people’s lives   in jeopardy, and will help further prevent the  transmission of   HIV/AIDS by keeping victims and prison supervisors  informed when   inmates test positive for the virus.” 
   State  Attorney General Andrew Cuomo has announced that he is   seeking, under  New York’s Sex Offender Management Act, to   have Williams confined in a  state-operated psychiatric   facility. 
   Senator  Young said, “Nushawn Williams is the poster   child for why we need a  civil confinement law in New York State.   I urge Attorney General Cuomo  to do everything in his power to   ensure that Williams remains  confined. This deadly predator must   not be returned to society.” 
   Senator Young’s legislation would create the crimes of    reckless endangerment of the public health in the 1st and 2nd   degrees  for people who test positive for HIV/AIDS and then   recklessly engage  in conduct which results in transmission of   HIV/AIDS to another  unsuspecting person or puts that person at   substantial risk of  contracting HIV/AIDS. 
   The bill would also, among  other provisions, required persons   charged with a sex offense or  reckless endangerment of the public   health to be tested for HIV/AIDS  and the results to be available   to the victim (s) upon request. 
   The announcement in the fall of 1997, that Nushawn Williams    had been informed of his HIV-positive status but continued to   have  unprotected sex with numerous women and underage girls in   Chautauqua  County, shocked the state and the nation. Williams was   directly  responsible for infecting thirteen victims statewide   with HIV, two of  whom passed on the virus to their children. 
   Williams  completed his 12-year sentence for reckless   endangerment and two  counts of statutory rape last Tuesday, but   continues to be held at  Wende Correctional Facility in   Alden. 
   While in  prison, Williams tossed his HIV-tainted urine at   another inmate, said  he wanted to infect more women with HIV when   he is released, fought  with other prisoners, engaged in gang   activity, and arranged to have  drugs smuggled in and used them.   He did not complete any sex offender  or drug treatment   programs. 
   In a required  pre-release psychiatric evaluation, Williams   was found to be  antisocial, psychopathic, lacking in remorse and   “prone to further  sexual contact with underage individuals   because of deficits in his  emotional capacity to understand why   this is wrong.” 
   Specifically,  Senator Young’s legislation (S. 3407)   would: 
   –  Create the crime of reckless endangerment of the public   health in the  1st degree, a class B felony, for those who are   aware that they have  tested positive for HIV/AIDS and then   recklessly engage in conduct  which results in transmission of the   virus to another person who is  unaware of the condition. Also   creates the crime or reckless  endangerment of the public health   in the 2nd degree, a class C felony,  for those who have tested   positive and then engage in conduct which  creates a substantial   risk of the transmission of HIV/AIDS to another  unwitting   person; 
   – Create a class E felony for  providing false information or   statement regarding HIV status to a  health care provider; 
   – Require all currently  incarcerated persons and persons   newly entering a correctional
facility be  tested for the HIV   virus; 
   – Provide that a person  charged with a sex offense under   article 130 of the State Penal Law or  reckless endangerment in   the 1st or 2nd degrees must be tested for  HIV and the results of   the test made available to the victim (s) and  defendant upon   request; 
   – Provide that upon the  diagnosis of an inmate with HIV/AIDS,   notice of the diagnosis must be  provided to corrections personnel   and others involved in the  supervision and care of the inmate to   that they can take appropriate  measure to protect themselves and   other inmates from exposure.
