Kim Wolfe entered the plea Wednesday to two counts of murder, one count of kidnapping, assault and a weapon charge. The judge said he will sentence her to 22 years to life on Nov. 2.
Stacie Williams, a 45-year-old nurse's aide, was gunned down last year outside the Nassau University Medical Center in East Meadow. The pair had met to discuss a possible reconciliation.
Wolfe then went to a relative's home about three miles away in Hempstead. There, she killed her uncle, wounded her 88-year-old grandfather and took a 23-year-old niece hostage following a dispute over life insurance policies. The niece was not harmed.
